Small UAV detection at a 3.5 km distance with ASTROHN thermal imageradmin
The detection of unmanned aerial vehicles (UAVs) has become an increasingly urgent and acute problem in recent times.
Continuous improvement and expansion of the scope of UAV application multiplies the number of possibilities for their illegal use. The objectives of the application are espionage and terrorist acts. In addition, they are already used in the army, as reconnaissance and attack aircraft. The small size and low efficiency of the reflective surface make modern UAVs an extremely inconvenient target for detection systems: the detection range and, accordingly, the response time to the detected threat are reduced.
To effectively counteract small UAVs, ASTROHN Technology Ltd, together with partners, is developing combined detection systems that include several devices (a locator, a video camera, etc.) operating together under the control of a single hardware-software system. One of the main components of such systems is a thermal imager, as the most universal means of detection, operating continuously and in various weather conditions.
Recently, field trials of ASTROHN thermal imagers were completed, aimed at determining the detection range of small UAVs. The results are impressive: a 80×30 cm UAV was detected by a rotary system based on ASTRON-640A17/200/M module at a distance of 3.5 km! UAVs were also followed using a video analytics system for thermal channel imaging up to ranges of 3.5 km! The system based on the IRidium II-640/MP/75/M thermal imaging module detected UAVs with a diameter of 0.8 m at a distance of 1.9 km. The tests used ASTROHN 7-14 μm, 75 mm/1.0/M and 200 mm/1.4/M IR lenses.
ASTROHN Technology Ltd has been constantly improving its products and is open for cooperation.
