| 摘 要： | 提出了一种直观、易于实现的方法完成任意阵型声呐混响信号的仿真,采用空间非均匀方式分布散射元,直接对散射元的回波信号进行叠加.该方法适用于任意的发射波形.仿真综合考虑了多种影响混响的因素,包括发射信号本身的参数,声呐平台的运动.海洋环境等.通过比较和检验仿真混响与试验混响的相对混响级、瞬时值和包络值概率密度分布、空间相关系数,空时二维谱几个方面的特性,证明了仿真的有效性.该仿真数据能够满足空时自适应处理(STAP)等新的信号检测方法研究的需要.

| Abstract: | An intuitive and easy-implemented approach of simulation of sonar reverberation with arbitrary array shape is proposed,which uses the nonuniform distribution of scatters in space and the direct superposition of the scatters' echoes.This approach is applicable to arbitrary transmission waveforms.Many factors which will influence the reverberation are considered in the simulation such as the parameters of transmission signal,the motion of the platform,the ocean environment,etc.By comparing and testing the cha... |
