| 摘 要： | 经典的单元散射模型混响仿真方法无法应用于主动声纳空时自适应处理（space-time adaptive processing,STAP）算法研究。提出了一种基于单元散射模型的适合主动声纳STAP算法研究的圆柱阵混响仿真方法。根据声纳发射信号的距离和多普勒分辨力将海洋空间划分成若干个散射单元,将每个散射单元对各个通道混响的贡献在时域分别进行求和,得到各个通道的混响时间序列。仿真综合考虑了多种影响混响的因素,包括发射信号的参数、声呐平台的运动、海洋环境等。对仿真结果的空时特性进行了分析,结果表明仿真数据能够满足STAP算法研究的需要。

| Abstract: | Classic approaches of reverberation simulation based on the model of scatterer cell can not be used in the research on space-time adaptive processing.An approach based on the model of scatterer cell to the simulation of reverberation for an active sonar with cylindrical array is presented to test the algorithms of space-time adaptive processing(STAP).The ocean space is divided into some scatterer cells according to the range and Doppler resolution of sonar signal,and the time series of reverberation of each... |
