ABSTRACT:
A low cost system using passive radiometry or active radar for the detection of a target and providing discrimination between desired targets and false targets. The device may be mounted on a drone aircraft or other vehicle and comprises a detecting sensor having a fixed antenna system whose function is to detect the presence and direction to a target in airframe coordinates. The sensor provides means for generating a broad fan beam containing a plurality of closely spaced interference lobes spaced so as to encompass a predetermined target size. The interference lobes are continuously swept across the line of travel and the receiving circuitry provides means for detecting a desired target within the interference lobes. The system also provides a pre-programmed means, initiated by the target sensor, designed to aim the aircraft at the target and a target tracker or homing means having a fixed antenna directed along the heading axis of the drone aircraft and used to "home" the aircraft into the target.
