摘　　要：为了利用无源单站系统实现对运动目标定位与连续跟踪,提出基于最小二乘估计算法的运动目标无源定位跟踪方法。即利用均匀的等间距线列阵作为单个观测站,对多个运动目标进行方位和多普勒频率测量,在此基础上通过多点多次测量,采用最小二乘估计算法对非线性系统求解得到目标的定位解。仿真结果表明:该方法不但能够对多个运动目标进行定位,而且能够对其进行连续稳定的跟踪。To take advantage of passive single-station system for locating and continuously tracking moving targets,this paper presented a method of passive location and tracking based on least squares algorithm.Taking use of an uniform spaced linear array as a single observatory to estimate the target＇s orientation parameters and Doppler frequency,after many times measurement on multi-points,this method obtained the non-linear system＇s positioning solution through the least square algorithm.Simulation results showed that the method could not only locate and track multiple targets continuously and stably.
