| 摘 要： | 对水下静态小目标的声纳回波信号进行了仿真研究。针对水下静态小目标中典型的圆柱壳体加球冠形头部的结构,建立了该类目标声纳回波信号的亮点模型,以及声纳系统走航探测时的动态数据模型。在计算仿真数据时,将模型化的目标回波数据与真实的水声背景混响数据相融合,更真实的模拟实际情况。通过与湖海试实验结果的对比,该模型仿真效果良好,可以为声纳信号处理、水下目标识别等方面的研究提供支持。

| Abstract: | A simulation model of sonar echoes from a static underwater target is proposed.This model is based upon the typical shape of a cylindrical shell with a ball coronal head.The highlight model of echoes from sonar is built.And a dynamic model is set up for the sonar data when the ship is sailing.The simulated echoes of the target and the water reverberation from experiments are fused to make the results more realistic.Simulating results compared with some experimental data show that the model is practicable an... |
