本文首先分析了Rice杂波下目前的杂波图恒虚警处理器的性能,指出存在的问题。然后提出自适应门限杂波图恒虚警处理器及相干杂波图恒虚警处理器。计算表明,它们的检测性能可有很大的提高,甚至可完全消除杂波中稳定分量的影响。文章最后还讨论了杂波图处理中的其它一些问题。
In this paper, the performance of the current clutter constant false alarm processor under Rice clutter is analyzed and the existing problems are pointed out. Then the adaptive threshold clutter constant CFAR processor and coherent clutter constant CFAR processor are proposed. The calculation shows that their detection performance can be greatly improved, and even the influence of the stable components in the clutter can be completely eliminated. Finally, the article also discusses some other problems in the clutter processing.
