Abstract Tracking targets stably and precisely is the prior task of the accurate tracking radar. For the problem of instability of tracking filtering in the environment of nonGaussian noise and abnormal values caused by multitargets crossing, this paper starts from target tracking datas residual statistic property analysis, calculates the residual value by iterative ways, comes up with a method doing the trajectory filtering and controlling the target data correlation gate according to the residual value，and eliminates the abnormal values in real time. The simulation results show that the method is better than the compared one in terms of trajectory stability and precision with little computation increase.
