摘　　要：高重频脉冲多普勒雷达存在距离遮挡问题。分析了距离遮挡的特性,指出信号频谱的幅度趋势特性和离散特性可以用于辅助遮挡判决。在单重频的前提下,给出了基于记忆方法的抗遮挡跟踪的系统框架,设计了记忆跟踪滤波器与正常跟踪滤波器的切换机制。最后给出了微波暗室仿真试验结果。A range-eclipsing problem exists with HPRF-PD Radar. The features of rangeeclipsing are analyzed, hence come into being the proposal that the trend of signal spectrum peak magnitude and decentralization of Doppler frequency can be used to support the decision of eclipsing. On the occasion of single PRF, the framework of anti-eclipsing tracking based memory and the switching mechanism between memory and normal tracking filter is constructed. Simulation result in RF chamber is also presented to evaluate the performance of proposed method.
