摘　　要：针对高速度分辨率的雷达系统,提出了一种频率多分谱的地面人体目标点迹凝聚方法。在常规雷达经典点迹凝聚处理算法的基础上,深入分析经过脉冲压缩、滤波、恒虚警检测(CFAR)后的地面人体目标回波有效数据在距离、频率、方位上的分布特性,在频率维运用频率多分谱的方法,在距离、方位维运用包络加权的方法,给出了一种高速度、距离、方位分辨率下的点迹凝聚算法。实际工程实现验证了这一算法的可行性。The algorithm of plots agglomeration based on frequency split spectrum for ground human target is proposed for the high velocity resolution radar system. On the basis of conventional plots agglomeration, By analyzing the distributing characteristic on of echo data for human target which processed pass through pulse compression, MTD filter and CFAR, as well as applying the frequency split spectrum on the frequency dimension, envelope weighting on the range and azimuth dimension, the algorithm was referred on the high velocity, range and azimuth resolution. The realization in the engineering verified the correctness and validity of the proposed methods.
