Abstract : The patent describes an apparatus where part of the output of an active signal generator is delayed, phase shifted and recombined with the remainder of the output to form an input to an echo generator. Part of the output of a passive signal generator is likewise delayed, phase shifted and recombined with the passive signal generator output prior to being combined with the output of the echo synthesizer to provide signals simulative of multipath sonar characteristics. A controllable delay network utilizing shift register means is disclosed.
