Design of the Active Sonar Responder

The active sonar responder can provide coordinate target for the development, the test and the acceptance of the active sonar. The paper analyzes the characteristics of typical active sonar signal briefly. Then the active sonar responder is designed. The hardware design and the software design are enlarged on. Finally the responder is verified in an anechoic tank. The results indicate that the echoed signal generated by the active sonar responder designed can simulate the target strength, target distance and target speed accurately.
