摘要
测向交叉定位是一种典型的无源定位方法,在电子侦察中广泛使用,但在复杂地形环境下对目标定位过程中由于反射引起的电磁波多径传播会造成较大的监测站测向误差,导致虚假定位点的产生。针对这一问题,提出了基于接收信号强度(Received Signal Strength,RSS)辅助排除虚假定位点的方法,利用RSS定位特点划定信号源经纬度置信范围,并通过仿真与实测数据分析,定量地展示了该方法的有效性。
Direction-finding cross location is a typical passive location method,which is widely used in electronic reconnaissance.However,the multi-path propagation of electromagnetic wave caused by the reflection in complex terrain environment will lead to the direction finding error of monitoring stations,and the false location points are generated when the direction finding data with large error are used to locate.In order to solve this problem,a method of eliminating false location points based on RSS(Received Signal Strength)is proposed.The characteristics of location method based on RSS are used to define the confidence range of longitude and latitude of signal source,and the effectiveness of this method is quantitatively demonstrated through simulation experiments and analysis of measured data.
