摘　　要：恒虚警处理技术(CFAR),是用来在杂波环境变化的时候维持雷达虚警概率基本不变。当高分辨率雷达在低视角观察的海杂波或者地杂波背景中进行检测时,目标就是包含在非瑞利杂波中。最常用的描述非瑞利包络杂波的统计模型是 Weibull分布模型。通过 matlab 仿真平台,分别对有无目标的 Weibull 分布杂波环境进行最大选择恒虚警(GO-CFAR)处理,依此研究其有效性。Constant False Alarm Rate （CFAR） technology is used in radar to maintain control of the false alarm rate in the face of local variations in the clutter background noise level. When the high resolution radar is detecting an object in low angle of view of sea clutter or ground clutter, the object is covered by non-Rayleigh clutter. The most common and important description of non- Rayleigh clutter is Weibull distribution model. The effectiveness of the GO-CFAR processingin Weibull clutter background both with and without targets is studied in matlab.
