杂波图CFAR平面技术在均匀背景中的性能

Performance of Clutter Map CFAR Plane Technique in Homogeneous Background

典型的杂波图恒虚警检测技术常被用于时域平稳、空域变化较剧烈的杂波环境它在每个杂波图单元处都形成一个独立的检测阈值，于是被称为杂波图CFAR点技术．而沈福民提出了一种杂波图CFAR平面技术的构想这是一种在时空两维变化都比较平稳的杂波环境情况下尤为适用的杂波图CFAR检测技术，我们将其称为面技术本文具体推导了这种技术在时空两维都均匀的背景中的检测性能表达式，并同杂波图点技术的性能进行较细致的分析比较．结论表明。

The coventional clutter map CFAR method is often used to detect targets in a temporally stationary and spatially nonhomogeneous background. It averages radar returns temporally over several radar scans to form estimates of the mean background level for each clutter map cell. so it's called as clutter map CFAR point technique. A new approach of clutter map CFAR plane technique was proposed by Shen Fuming[1], which can be applied in a temporally and spacially homogeneous background. and is called plane technique. An analytic expression of detection performance of this technique is derived, and a performance comparison to clutter map point method is also given. It's shown that the performance of plane technique is superior to that point method in a temporally and spatially homogeneous background.
