A robust CFAR algorithm in non-homogenous enviroments

A new constant false alarm rate (CFAR) detection processor is presented that exhibits a robust CFAR performance in the condition of non-homogenous environment. Its performance would be independent of background noise power. Since the processor can track noise power variation and adopt itself to the new background conditions. The new CFAR algorithm, called as Adaptive Switching CFAR (AS-CFAR) is analysed and simulated CFAR to demonstrate its improved robustness in non-homogenous environments.
