Elint Aircraft - A surveillance aircraft is an aircraft used for surveillance. They are used by military forces and other government agencies in roles such as intelligence gathering, battlefield surveillance, aerial surveillance, reconnaissance, reconnaissance (eg weapons detection), border surveillance and fisheries protection. This article focuses on aircraft used in these roles, rather than traffic surveillance, law enforcement and similar duties.

Surveillance aircraft typically carry no weapons, or limited deterrent weapons. They do not always require high-performance capabilities or privacy features, and can be modified by conventional aircraft. Surveillance aircraft have also included tethered balloons (eg, TARS) and unmanned aerial vehicles (UAVs).

The name of the global hawk family of the US. it. DoD - RQ-4 - may believe the original designation of Block 40. "R" is the Patagonia designation for recovery, .... but the original designation ... is surveillance, not tracking. ... Exploration operations are generally intended for long-term intelligence-gathering purposes. The surveillance function is very important in the execution chain, with tactical operations providing a short-term decision-making process.[1]

For surveillance, it is important that the collection system, the target, and the decision maker communicate in such a way that AMI actions are communicated in real time to decision makers. to oppose Amy's actions.[2]

The terms "surveillance" and "reconnaissance" are sometimes used interchangeably, but, in the military context, a distinction can be made between surveillance, which monitors a changing situation in real time, and reconnaissance, which captures a static image for analysis.

In 1794, during the Battle of Fleur, the balloon of the French Aerostatic Corps L'Treprent remained afloat for nine hours. The French police used a balloon to watch the movement of the Austrian army, dropped notes on the ground to be collected by the French army,

One of the first aircraft used for surveillance was the Rumpler Taube during World War I, where Fred Zin pioneered new methods of reconnaissance and photography. The aircraft's flexible wings make it very difficult for ground-based observers to see the Taube at altitudes above 400 meters. Perch also called the plane "the invisible plane", and it is sometimes called "the first plane around the world". German Taube planes could see the increased Russian army in the Battle of Tannenberg (1914).

Mind The Gap

During World War II, light aircraft such as the Auster were used as aerial observation posts. British Royal Artillery officers are trained as pilots to fly AOP planes to locate artillery.

The aerial observation role was generally taken over by light observation helicopters, such as the Hughes OH-6 Cayuse, from the mid-1960s.

Before the war, the British saw the need for an aircraft that could remotely track and spot enemy ships. Of these designs the low-flying Airspeed Fleet Shadower and the General Aircraft Fleet Shadower were built and flown in 1940 but were rendered obsolete by the introduction of airborne radar.

Spy planes were a source of great conflict between the United States and the Soviet Union in the 1960s.

Naval surveillance aircraft are typically large, slow-moving machines that can fly continuously for hours, with a wide range of missions. Such aircraft include the Hawker-Sideley Nimrod, Breguet Atlantic, Tupolev Tu-95, Lockheed P-2 Neptune and Lockheed P-3 Orion/CP-140 Aurora. From the First World War to the Second World War, small ship-launching seaplanes were used.

Unmanned aerial vehicle (UAV) surveillance aircraft are "in use or under development in many countries, including Israel, the UK, the United States, Canada, China, India, South Africa and Pakistan."

Drones are increasingly used in conservation work to complete tasks such as mapping forest cover, tracking wildlife and enforcing environmental laws by catching loggers or poachers.

Some countries are adopting aircraft to meet electronic intelligence (ELIT). The Beech RC-12 Super King Air and the Boeing RC-135 Rivet Joint are examples of this work.

It has two main components - Communications Intelligence (COMINT) and Electronic Signals Intelligence (ELINT).

As its designation suggests, COMINT involves the consideration and analysis of communications between organizations, military units, and individuals. A subset of COMINT is traffic analysis—a process that involves determining the flow of traffic between organizations, units, and individuals, and the amount of traffic involved. Traffic analysis is still useful even if the signals it reads are encrypted and cannot be deciphered.

Elint Aircraft

ELINT stands for intelligence gathering through interception and non-communication signals research. This includes transmission of radar systems, missile guidance systems and IFF detectors and transponders. ELINT functions will intercept such signals, and will attempt to determine the power, operating procedures, and hardware locations from which they originate.

Weapon system sensors are becoming more sophisticated, with higher resolution, increased data rates, and more complex data. Signal density is increasing, along with a growing number of commercial applications using frequencies similar to those for military applications. SIGINT and COMINT software must be able to cope with these changes.

They must be able to deal with immediate threats, while low probability of intercept (LPI) radars using techniques such as frequency-modulated continuous wave (FMCW) pose problems for older ELINT receivers. These may have difficulty finding, analyzing and identifying such symptoms.

However, given the long service life of many military equipment - the S-75 DVINA (SA-2 GUIDELINE surface-to-air missile entered service in 1957, but is still in service with about 20 users - SIGINT systems must also face This obsolescence in cases, the weapons are upgraded, so they may have a different electronic signature than the original variant.

Uae's Advanced Intelligence Aircraft Begins Operational Testing

At the same time, SIGINT receivers must also be able to handle the high signal density created by the ever-increasing number of emitters, and cover ever-higher frequencies, including the millimeter wave bands. Therefore, while older threats may be effective, older ELINT receivers may have reduced usability.

For larger forces, the classic SIGINT aircraft platform is often based on long-range transport aircraft. The best known example is probably the USAF version of ​​the RC-135V/W RIVET JOINT for the Boeing RC-135.

The UK's fleet of three NIMROD R.1 SIGINT aircraft was decommissioned in 2011, and the resulting gap was filled until 2017 when the Royal Air Force received the first of three based on the RC-135W and known as the AIRSEEKER R. . 1. The Royal Air Force also operates an eight-seat version of the SHADOW R.1, surveillance, target acquisition and intelligence (ISTAR) Beechcraft KING AIR 350 aircraft. Last year, the UK MoD awarded Leonardo and Thales contracts to provide DAS integrated that knows. To protect the aircraft from IR-directed threats.

First flown in 1958, the Ilyushin Il-20M COOT-A SIGINT aircraft is a military version of the Il-18 turboprop-powered aircraft. A batch of 20 was created, and the brand is still active in Russia. The aircraft is reported to conduct the ROMB 4 SIGINT program and the VISHNAYA COMINT program.

First shown at the MAKS air show in 2013, the Tupolev Tu-214R is intended to replace the Il-20M. It carries the MRC-411 multi-intelligence system, which includes SIGINT sensors, side-looking synthetic aperture radar (SAR), and multi-spectral electro-optical systems.

In 2004, France chose to retire its two system airport de recoil d'informations de guerre électronique (Sarigu) Sigint aircraft. Based on the DC-8 aircraft, it carried a sensor suite developed by what was then Thompson-CSF. The avionics development by Thales was reportedly over budget and had a weight problem, factors that may have contributed to the decision to cancel the flight. With the end of the Sarigue program, the only French ELINT aircraft are two older versions of the C-160G GABRIEL SIGINT TRANSALL transport. Both are expected to retire in 2025.

Like several other countries, France saw the need to install a next-generation SIGINT aircraft based on a thin airframe - a move made possible by the reduction in size and weight in modern electronic equipment, and the capability of high-speed data links that Would allow SIGINT experts to sit on the ground rather than being carried on board. In 2018, the French MOD ordered Dassault Aviation to supply three FALCON business jets equipped with Capacité Universelle de Guerre Électronique (Universal Electronic Warfare Capacity) SIGINT systems developed by Thales.

When a person is immersed in water, within seconds the body begins to reflexively change. Heart rate slows down. Blood vessels in the limbs constrict, blocking blood flow to vital organs. And, crucially, the spleen contracts, releasing precious oxygen-laden red blood cells into the bloodstream. All of this extends the amount of time we can go without gasping.

Now, new research suggests that some sea creatures may have evolved over thousands of years to push the limits of their normal diving response. A study by an international team of researchers found that a genetic change allowed a population in Southeast Asia to grow a larger spleen that could improve their ability to hold their breath. Some scientists have compared these evolutionary changes to Tibetans being able to thrive at high altitudes.

The new study dealt with people locally often referred to as "sea nomads," who live on the islands and coasts of Southeast Asia. "Traditionally, they live in houseboats and occasionally come ashore. "They're known for being amazing divers and their connection to the sea. I've dived with them and their abilities are just unreal."

In the waterways between the Philippines, Malaysia and Indonesia, divers among the Bajau who live in houseboats have been recorded holding their breath for more than five minutes while hunting fish or shellfish. In contrast, average people can stay underwater for 1-2 minutes, whereas world-class freedivers can hold their breath for up to 3-4 minutes in competitive situations.

Previously, the crew from the BBC documentary series Human Planet recorded a Bajau hunter diving and noted that his heart rate dropped to 30 beats per minute. (Most people's dive reflex only drops the heart rate to around 50 beats per minute in healthy adults.) "They've seen them dive more than 70 meters with just a weight belt and a set of goggles," says Ilardo. “If you were just collecting clams at 10 meters, you could spend an entire day in a shallow dive like this. While diving at a certain point, [Bajau Friend] looked down and saw a large clam. He immediately dropped another 15 meters and caught it. Pretty amazing."

As an evolutionary geneticist, Ilardo wanted to know if Bajau's abilities were the result of training at birth or if he had become an elite diver through generations of marine life. So she asked the Bajau, along with the Saluan, a group of genetically similar farmers, to sequence their genomes and measure the size of their spleens. A larger spleen can store more oxygen-rich red blood cells, allowing divers to stay underwater longer. “There was a portable ultrasound machine. I gave it to the village and people came and measured their spears,” she says. 43 Bajau and 33 Saluan participated in the study;

The Bajau had a much larger spleen than the non-diving Saluan, says Rasmus Nielsen, a computational biologist at the University of California, Berkeley, and lead author of the study. "We found that the Bajau had a spleen that was 50 percent larger," he said. However, among Bajau itself, divers had slightly larger hoards (about 10% larger) than those who abandoned the traditional diving lifestyle. This finding raised the possibility that the cause of Bajau's larger spleen was genetic, rather than lifelong aquatic training.

Next, the researchers searched the Bajau genome for signs of natural selection and found 25 genetic variations that appear to be unique to this population. When Ilardo and her colleagues cross-referenced the genes involved, they found that some of them appeared to be related to respiratory arrest and oxygen deprivation. “[It] was very interesting to see all the genes that might be suitable for diving get selected,” says Ilardo.

. "We know that this gene controls thyroid hormone levels and controls spleen size," Nielsen said. Less than half of the Bajau have a version of this gene associated with larger bulls, compared to 6% and 3% of the Saluan. Han Chinese (a group chosen for comparison because the two groups are not closely related), e analysis suggested two different genes that evolved in the Bajau.

It helps regulate the balance of carbon dioxide in the blood. According to the researchers, both may be important for oxygen conservation and the ability to hold your breath underwater.

The new study provides a striking example of human genetic diversity and adaptation to aquatic environments, said Anna Di Rienzo, a population geneticist at the University of Chicago who was not involved in the study. "It's obviously a big deal and very important work," she says. “I thought it was a very interesting story about people living in very different real-life environments.”

But Di Rienzo says researchers will need extensive follow-up to understand how the 25 genetic variants her team identified behave differently in the Bajau. They still need to "find out more precisely how the genes they propose actually affect physiology and the ability of divers to do this," she said. For now, Ilardo and her colleagues only know that these genes are different in the Bajau. It is still not clear what most of the genes that confer a diving advantage do.

Evolutionary anthropologist Cynthia Beall says that part of that research should go back to the Bajau and Saluan communities and go beyond the size of the spleen to collect more physiological measurements, such as carbon dioxide and oxygen levels in the blood. University wasn't like that. Engage in research. “A reasonable hypothesis is just a starting point, but there are data to be had before we can tell all these biological stories,” says Beall. "How does their blood oxygen saturation drop during an average dive?" heart rate?” This data can reveal just how much stress Bajau divers put on their bodies when hunting and how their unique genetics translate into underwater prowess.

Ilardo and Nielsen agree and plan to return to Indonesia to continue learning Bajau. Ultimately, they say, this work could help uncover new clues about how people react to lack of oxygen, an important knowledge in medical situations such as surgery.
