摘　　要：三维被动定位是ESM系统的重要内容,在军事上是侦察定位、监视监测的重要方面。AOA是被动雷达普遍采用的一种定位方法。基于安装于不同运动平台上的两个传感器的AOA测量,给出了ILS融合算法。仿真结果显示采用AOA融合算法,使定位精度得到有效提高。3D passive location of radar emitters plays an important part in electronic support for military surveillance. The AOA （angle of arrivals） is one popular scheme for passive emitter location. In this paper, a location scheme is proposed based on fusion of AOA measurements from two ESM （electronic support measures） sensors installed on two moving platforms, respectively. Furthermore, ILS （itemtive least-squares） is also proposed to fuse AOA measurements from two ESMs. Experimental results show that the location accuracy of the radar emitter can be improved effectively by this AOA fusion algorithm.
