| 摘 要： | 针对单参数CFAR检测器在Weibull杂波下需事先估计杂波的形状参数,而双参数CFAR检测器如Log-t CFAR等则存在虚警损失较大的问题,基于有序统计（OS）CFAR检测器,结合反馈控制理论,提出了一种适用于Weibull杂波模型的双参数CFAR检测器.理论分析与仿真表明,该检测器无论在均匀背景还是非均匀背景下都具有较好的检测性能. |
| 关 键 词： | 恒虚警率 Weibull杂波 反馈控制 CFAR损失 检测性能 |

| Abstract: | Targeted at the problems that the clutter shape parameter needs to be estimated in advance in a single parameter CFAR detector under the Weibull clutter,while there exist a larger CFAR loss in double parameter CFAR detector,such as Log-t detector,a sort of biparametric CFAR detector suitable for Weibull clutter model was presented,based on the OS CFAR detector and combined with the feedback control theory.The theoretical analysis and simulation show that the detector is of better detection performance under the uniform and/or non-uniform environment. |
| Keywords: | CFAR Weibull clutter feedbak control CFAR loss detection performance |
