The apparatus is for training submarine personnel in the detection of water craft by sonic apparatus including the use of receiving devices adapted to detect and reproduce the various sounds made by or reflected from a surface water craft. Wake echoes differ from echoes of the water craft and training is required to tell the difference. Four signals are derived carrying varying wave characteristics. These signals and a signal characteristic of own-ship's speed are fed to elements to obtain an output signal corresponding to that obtained from a real wake by sonar equipment mounted on a ship.
