Abstract: The proposed simulator of a target which moves relative to a moving object comprises a synchronization means to form signals corresponding to the variable azimuth of the direction of space, scanned by radar installed on the object and to the variable distance of scanned space points; and a group of transducers to form signals which carry information on the course and speed of the object. The transducers are connected to a channel for forming a signal to simulate the target. The channel comprises a group of transducers to form signals carrying information on the true course and actual speed of the target, and a computer to form signals carrying information on the azimuth of the target and the distance between the target and the object. The channel further includes logical circuits to form pulse signals whose timing in relation to respective reference pulses corresponds to the azimuth of and the distance to the target.
