ABSTRACT:
Sonar echoes of length s/c (cos .theta..sub.i +cos .theta..sub.r)+T are slated by transmitting properly timed replicas of an illuminating signal from a number of projectors spaced along a cable of target length s. Because of the length of this cable, magnetic anomaly effects can be simulated by passing a current through a conductor within it.
