| 摘 要： | 传统的恒虚警率(CFAR)检测器鲁棒性较差，为此，提出一种基于AD检验的CFAR检测器AD-CA。通过Monte Carlo仿真得到AD检验的临界值，并删除异常样本。仿真结果表明，在均匀背景下，AD-CA的检测性能与OS检测器相当；在多目标背景下，AD-CA的检测性能比OS检测器有所提升，当干扰目标个数大于N–k时，仍能保持较好的检测性能。

| Abstract: | For solving the robust disadvantage of the existing Constant False Alarm Rate(CFAR) detectors,a new CFAR detector based on Anderson-Darling(AD) test called AD-CA is proposed.It takes the critical value of AD test through Monte Carlo simulation,then deletes the unwanted samples.It is evaluated through simulation in various environments.Simulation result shows that,in homogeneous background,the performance of AD-CA is as good as OS;In multiple targets background,compared with the OS,the detection performance of AD-CA improves obviously.Especially when the value of interfering targets exceeds N-k,it also keeps good performance. |
