摘要
针对机载预警(AEW)雷达多杂波分布模型的恒虚警检测问题,提出一种自适应单元平均恒虚警(ACA-CFAR)检测方法.这种检测方法是在经典CA-CFAR检测方法基础上加入自适应判断选择背景参考子窗的一种CFAR处理方法.它是根据杂波功率水平的变化选择背景杂波单元,在此基础上结合CA-CFAR检测方法实现检测.仿真结果表明,ACA-CFAR恒虚警检测方法在均匀背景和多目标背景下均具有较好的检测性能,并且运算量小.
Concerning CFAR detection for multi-class clutter distribution based on AEW radar, a method of adaptive CA-CFAR detection was presented. The detector joined adaptive judgments and choice module based on classic CA-CFAR. After being judged and choosed background region for average of clutter region data, it employed CA-CFAR detector. Results show that the method has a good detection performance not only in homogeneous environments but also in multi-target interference environments, and its operation work is not much.
