A means for synthesizing echoes using a combination of analog and digital techniques for target classification training of shipboard ASW men was needed. A study indicated that the echoes could be generated by using the latest state-of-the-art methods and components. A system incorporating solid state components was designed and implemented to produce a synthetic sonar echo. The finalized research tool was then evaluated at the Key West Fleet Sonar Training School and at the Naval Training Equipment Center, Orlando. Installation of a prototype trainer in a Navy Sonar Training School is recommended. Training effectiveness studies should be conducted in order to determine the full extent of training transfer from the simulator to the real world situation. It is further recommended that this study be continued to include the effects on the echo signal due to multipath propagation and reverberation. Methods should be investigated to feed the echo signal to the sonar set receiver processor input on a non-programmed basis. This would include additional electronics or a mini-computer to solve target motion and position relative to own ship.
