Abstract
The target strength is an important parameter of underwater acoustic countermeasure.Target strength is measured by using single-frequency signal in shallow water waveguide,and the result of measure is dispersed by reason of undulating.Simulation result shows that it can reduce the undulating and heighten precision of target strength measurement using 10% bandwith narrowband signal.
