Ukrainian scientists have developed a radiometric remote sensing system for all-weather detection of drones. The development of the staff of the National Aerospace University named after Zhukovsky "Kharkiv Aviation Institute" was presented at the Sikorsky Challenge-2021 festival of innovative projects [...], Defense Express reports.
The device is designed to probe waves in the X, Ka, and W ranges. During operation, the passive radiometric complex does not emit waves, which complicates its detection by radar means.
According to Eduard Cerne, an engineer at the Department of Aerospace Radioelectronic Systems at the KHAI, the complex detects radio-thermal radiation from an unmanned vehicle, which is almost impossible to get rid of. Even in radio silence, the heated drone emits a wide range of waves, Cerne added.
The detection device is compact, which makes it difficult to visually identify it. In turn, the Ukrainian development can detect a micro-drone at a distance of 1200 meters during rain, and up to 2500 meters - in clear weather. The detection range increases in proportion to the size of the target — so, the largest drones can be "seen" by the complex at a range of 16.5 thousand meters, the authors of Defense Express say.
According to the developers, one complex is able to detect the direction of the drone's flight, and to establish the exact location of the target, at least three stations are needed. The military is already interested in the development, the tests of which can begin in the near future, Cerne added.
Earlier it became known that the experimental machine of the Russian robotic platform "Marker" made a march in autonomous mode. The car passed 100 kilometers of off-road and dirt roads.
