Abstract: A system for bistatic radar target detection employs an unmanned aerial vehicle (UAV) having a radar antenna for bistatic reception of reflected radar pulses. The UAV operates with a flight profile in contested airspace. A tactical fighter aircraft having a radar transmitter for transmitting radar pulses operates with a flight profile in uncontested airspace. A communications data link operably interconnects the UAV and the tactical fighter aircraft, the communications data link transmitting data produced by the bistatic reception of reflected radar pulses in the UAV radar antenna to the fighter aircraft.

Abstract: A projectile toy includes an elongate body having an internal cavity, to include wing plates that are arranged for pivotment from a first position positioned within the cavity to a second position directed exteriorly of the cavity in a timed relationship to project the wings from the body upon directing the toy from a catapult alone or in combination with a propulsion member.
