Drone "Avenger" for the first time autonomously tracked targets using infrared instead of radar

Typically, radar is used to detect and track air targets by aircraft or drone. It's comfortable,

not always. For example, it must be turned off so that the enemy does not discover its location. Also, the radar signal is not protected from natural or intentional interference.

To solve this problem, LockheedMartin developed the Legion Pod targeting and reconnaissance system, which has already been used on the F-16 and F-15C fighters. The unit, 2.5 m long and 41 cm in diameter, is equipped with an IRST21 passive infrared sensor, which replaces the active radar. By detecting infrared radiation, the system processes the data and tracks external targets.

Legion Pod is equipped with standard interfaces,therefore, no major modifications are required to install it on an aircraft. Therefore, the integration of the Avenger drone with the software platform took only 90 days. The interaction of the system with the drone platform is ensured by the Open Mission Systems (OMS) system messages standard. This ensured a quick and cost-effective installation

During the Avenger test flightdiscovered several aircraft that were moving at high speed. The drone also analyzed the tracking data and carried out a series of maneuvers necessary to hit targets.
