摘　　要：本文根据频率步进高分辨率雷达目标的一维距离像提出一种新的信号检测方案 ,即先从目标的距离像中提取散射中心 ,获得其空域散射密度 ,再进行广义似然比检测。文中第二部分为得到目标的空域散射密度研究了需从距离像中提取强散射中心的算法 ,第三部分分析了基于目标空域散射密度的广义似然比检测 ,最后进行仿真实验 ,结果表明 。In this paper,a novel scheme of radar target detection is proposed according to the high range resolu- tion radar targetrange profile.That is extracting scattering centers from range profile firstly,then process with the generalized likelihood ratio test (GL RT) .In Part ,an algorithm to extract scattering centers is proposed. Based on spatial scattering densities,the GL RT detection is studied in part .At last,simulative experimentis developed,simulation results indicate that the detector has effective detection performance.
