Abstract
The target simulation system includes a reflector 18 located within a closed and shielded room 10. An array 30 of transmitting elements is located within an opening 22 of the room so that the array is centered at a first focal point F.sub.1 of an ellipsoidal reflecting surface 18A of the reflector, and a receiving element of the target seeker 34 to be tested is located within an opening 24 so that the receiving element is centered at a second focal point F.sub.2 of the ellipsoidal reflecting surface. Phased array control system 32 causes the array to simultaneously and independently transmit a plurality of beams of radiation toward the reflector and each transmitted beam results in a corresponding reflected beam whose beam axis passes through the second focal point of the array so that each reflected beam simulates radiation coming from a distinct target. In the case where the radiation is electromagnetic radiation in the MMW range, the phased array control system (FIGS. 2 and 3) performs all phasing and modulation that is required for the steering and focusing of each beam and for the simulation of target range, target characteristics and target seeker characteristics at an intermediate frequency.
