With the draconian price of drones and the ease of operation, gradually everyone has access to this small aircraft. Unlike traditional aircraft, drones have three major characteristics: First, they have a relatively low altitude (approximately less than 400 feet), which allows them to hide themselves perfectly in a complex terrain; second, its speed of movement. It is also relatively slow (about less than 90 knots), which makes it difficult to distinguish them from other moving objects. Third, it is relatively small (less than 55 pounds), which makes them very Hard to see with the naked eye. These three characteristics make it very likely that drones will be used extensively in terrorist attacks and military-related fields. This is really worrying. You know, two months ago, British officials announced that they discovered that the terrorist organization ISIS had used commercial drones to launch explosive attacks on the Syrian and Iraqi troops. These drones also carry a surveillance camera. Terrorists can use the camera to map the enemy’s location. Â
Although the core area of ​​ISIS activities is about 6,000 miles away from the United States, the Defense Advanced Research Projects Agency (Darpa) still wants to prevent it. They want to ensure that such evil terrorist organizations do not attack their homes in the near future. . Therefore, the U.S. government plans to use a sniper drone surveillance system to crack down on drone crimes in urban areas.
Recently, Darpa launched a sniper drone surveillance project called the Aerial Dragnet. It can track all unmanned aerial systems flying above 1000 feet above the big city. At the same time, a flight system equipped with sensors can monitor the dynamics between buildings at high altitudes. In this way, even without knowing the exact location of UAVs, the system can accurately locate them, and thus combat them. Those based on drone attacks and other crimes.
In a statement published by Darpa, we learned that although various systems for tracking drones have been developed, these systems are not practical enough in complex urban landscapes--especially where the horizon is often obscured by buildings and trees. Area. Worse, many vehicles are moving at the same speed, which greatly interferes with the tracking system's real-time monitoring of the city's environment. Â
“Aerial Dragnet wanted to develop a system to adapt to the basic functions of small UAVs in urban areas, enabling non-line-of-sight tracking and identification of potential threats at slow, low-altitude flights. At the same time, Darpa could use data output from the Aerial Dragnet system. Draw a constantly updated airspace common operational map and transmit it to authenticated users via secure data links, explains Darpa.
Because the drone market is constantly expanding, Darpa may also include signal processing systems that can be recognized by software on low-cost sensors and install them on existing drones on the market. They expect to develop a system that can cover a seven square mile range with only one flight platform, and the cost of implementing its payload will not exceed $10,000.
There is no doubt that this is a revolutionary scientific and technological innovation, and it is also a replacement of military weapons worldwide. On the upcoming September 26th, Darpa will organize an event for citizens to contribute to the construction of a city-wide flight surveillance platform. Xiao Bian thinks that this form of brainstorming is excellent, after all, experts are in the folks.
