1. A method for bistatic radar target detection comprising:

  • launching an unmanned aerial vehicle (UAV) and navigating the UAV with a ramjet engine at supersonic cruise to beyond a radar range limit of a mothership aircraft;

    maintaining the mothership aircraft on a flight profile outside the radar range limit;

    extending antenna arms to act as air brakes reducing speed and providing boresight orientation of Tx/Rx modules for bistatic RF pulse reception;

    employing a high power radar system on the mothership aircraft to emit radar pulses;

    employing receive (Rx) modules on the UAV as a bistatic receiver to receive reflected radar pulses from targets; and

    ,transmitting target data from the UAV via a communications data link to the mothership aircraft.
