| 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．

| Abstract: | 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. |
