Abstract: A system for simulating a moving target, having an antenna that emits a steerable propagation pattern, a receiver and a target signal generator. Analog signals representing the azimuth position of the target and the azimuth position of the antenna propagation pattern are summed yielding analog azimuth position signals. The analog azimuth position signals are then converted to digital code. Analog signals representing the elevation position of the target and the elevation position of the propagation pattern are summed yielding analog elevation position signals. The analog elevation position signals are then converted to digital code. The azimuth position digital code and digital code representing the propagation pattern direction are input into a memory unit which outputs an azimuth attenuation digital code. The elevation position digital code and the propagation pattern direction digital code are likewise input into a memory to produce an elevation attenuation digital code.
