| 摘 要： | 无源定位是电子战系统的一个重要组成部分,基于非合作信号(如广播、电视信号)的定位技术相比传统的无源定位具有很大的优势,但该定位方法目前还存在一些技术问题.为此,提出采用基于典范相关分析的盲分离方法,来完成对强直达波环境下反射波的分离、提取和延迟时间的计算,再结合方位估计,就可将这种定位问题转换为时差-方位定位.用这种方法可获取优良的定位性能,实现起来也相对容易,同时计算量少.仿真试验结果表明,该方法能有效地解决这种新颖定位技术的相关问题,并为其工程实现打下基础.

| Abstract: | The location of emitter by passive sensor arrays has received considerable attention in recent years.It is an important component of electronic warfare(EW) system.To solve the problems concerning the location method based on non-cooperative sources such as broadcast & television signals,a new way of mainly applying blind source separation(BSS) was proposed based on canonical correlation analysis(CCA) to fulfill the signals separation,echo extraction,and computation of time diffe-rence in strong direct wave ... |
