| 摘 要： | 目标强度是水声对抗的重要参数之一.浅海波导条件下采用单频信号测量目标强度,传播起伏的影响会导致测量结果散布.仿真计算表明,采用10％带宽的窄带信号测量能够减小传播起伏,降低目标强度测量的不确定度.

| 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. |
