ABSTRACT:
An apparatus which simulates signals received by a radar antenna and which is used for teating radar equipment and for training purposes, Two stores are provided to hold the horizontal and vertical polar diagram characteristics of an antenna, respectively. The appropriate values are read out of these stores by signals representing the azimuth and elevation angles of an imaginary target and the antenna, which may be real or imaginary. The outputs from the stores are combined to give a realistic simulated signal. Since the polar diagram characteristics of an antenna may be different for transmission and reception, each store may be provided in duplicate and the outputs from all four stores combined to produce the simulated signal.
