| 摘 要： | 针对S-CFAR在杂波边缘虚警控制能力较差的问题,文中基于S-CFAR的检测单元统计特性和OS-CFAR的有序统计特性提出了SOS-CFAR,并按照一定的参数选择顺序对SOS-CFAR参数进行了选择,最后仿真对比了几种CFAR的检测性能及虚警控制能力。仿真分析表明,SOS-CFAR在均匀环境和多目标强干扰环境下的检测性能与S-CFAR相当,且在杂波边缘的虚警控制能力有较大的改善。 |

| Abstract: | In order to improve the control ability of FAR of S-CFAR at clutter transitions,a SOS-CFAR is presented based on the detection cell's statistic characteristic of S-CFAR and the order statistic characteristic of OS-CFAR in this paper.The parameters of SOS-CFAR also have been choosen according to a certain sequence.The detection performance and the control ability of FAR are compared between SOS-CFAR and many other types of CFAR lastly.Simulation shows that this CFAR has almost the same detection performance ... |
| Keywords: | CFAR parameter selection detection performance control ability of FAR |
