This invention relates to sonar target simulators of the type which can receive sonar pings and modify and reradiate the ping signals so as to resemble the sonar echo signal from a moving target ship. The object of this invention is to provide an improved sonar target simulator. The generation of a signal which, when presented on a display screen is indistinguishable from a genuine echo signal, has obvious tactical implications. The generator for such purposes can be employed in equipment for training sonar operators, or can be employed in an anchored or moving repeater for decoying the enemy.
