摘　　要：传统机载平台的定位技术一般采用多站协同或对机载平台辐射的具有固定帧格式的信号进行定位,存在一定局限性。针对舰载平台的特殊性,提出了一种基于舰载单平台的单站逆无源定位方法,利用方向信息、多普勒频率变化率以及相位差变化率对信息进行定位,并通过实际数据进行了侦收仿真,验证了该方法的有效性。As to the location technology of airborne platform, the conventional way of location contains multi-station co-location or the technique which the target emits signal in a specific format. All of those technologies have certain limitations. In view of the above, the method of inverse passive location based on shipboard is proposed which takes the particularity requirements of the shipboard into account. This technology utilizes the information of direction, Doppler frequency rate of change and phase difference rate of change to locate. The algorithm′s performance is proved through actual data simulation.
