| 摘 要： | 本文对典型水下目标回波信号进行了仿真研究。此仿真基于声纳目标回波的亮点模型理论,通过成分及时序分析,针对具有球冠形头部和圆柱壳体的典型水下目标的结构特征,建立计算模型并仿真回波信号。仿真结果与湖海试实验结果的对比表明此仿真模型与实际情况基本一致,可以为声纳信号处理、目标识别等方面的研究提供支持。

| Abstract: | A simulation model of echoes from a typical underwater target is proposed.This model is based upon the highlight model of echoes from sonar.The target has a cylindrical shell with a ball coronal head.The echo characteristics of the target are found by analyzing the component and sequence of highlights.A computing procedure is built and echoes are simulated.Simulating results compared with some experimental data show that the model is practicable and can be used in some practical situations. |
