空域CFAR处理方法综述

Survey of Space CFAR Processing

摘要:

综述了空域恒虚警(Constant False Alarm Rate,CFAR)处理研究的发展、现状和最新进展。首先,讨论了空域CFAR处理的概念及其在整个CFAR处理中所处的位置；然后,将空域CFAR处理算法分为ML类、OS类和自适应算法,介绍了每类CFAR算法的研究现状；最后,展望了空域CFAR处理算法的发展,指出了空域CFAR处理算法未来的几个发展方向。

Abstract:

In this paper, the history, current status and recent progress of the space CFAR (constant false alarm rate) processing were summarizes. Firstly the status of the space CFAR processing in CFAR techniques was discussed. Then the space CFAR processing methods were classified into three types, including mean level type, order statistics type and adaptive methods. At last, in view of current research situation, some prospective fields in the future were introduced.
