| 摘 要： | 在研究现代三坐标(3D)雷达中三维杂波图的形成原理的基础上,将各种恒虚警(CFAR)算法应用于轮廓杂波图中,得出采用有序统计(OS)算法不但可较好的对杂波建立标志,对杂波外的目标不建立标志位,且对慢速目标有较好的检测效果。此外,给出了其在现场可编程门阵列(FP-GA)中的实现。

| Abstract: | On basis of studying principle of forming 3D-clutter map in modern 3D radar,various constant false alarm（CFAR） algorithms are applied to profile clutter map,it is concluded that using the ordered statistics algorithm can not only build a better mark on the target inside the clutter,not build a mark on the target outside the clutter,but also has better detection effectiveness on the slow moving target.In addition,its implementation on field programmable gate array（FPGA） is given. |
