研究 Ｋ—分布杂波背景下的顺序统计恒虚警检测器的性能，分析检测器在均匀统计独立杂波背景下的性能，给出了理论门限系数值及其仿真的门限系数值，并讨论相关杂波的恒虚警性能。分析了检测器在杂波的边缘和存在多目标及干扰时的目标检测性能。从仿真结果分析得出， Ｏ Ｓ— Ｃ Ｆ Ａ Ｒ 检测器在杂波边缘及多目标情况下具有比单元平均恒虚警（ Ｃ Ａ— Ｃ Ｆ Ａ Ｒ）好得多的性能，特别是在参考单元比较少的情况下。
The performance of sequential statistical CFAR detector under K-distributed clutter background is studied. The performance of the detector in the background of uniform statistical independent clutter is analyzed. The theoretical threshold value and the threshold value of the simulation are given. Constant clutter related false alarm performance. The detection performance of the detector at the edge of clutter and in the presence of multiple targets and disturbances is analyzed. From the simulation results, we can conclude that the O S-C F A R detector has a much better performance than the unit-averaged CFAR at clutter edges and multi-objective conditions, especially at Reference unit is relatively small case.
