WebFeb 1, 1995 · Order-statistics (OS) is a constant false alarm rate (CFAR) technique which is relatively immune to the presence of interfering targets among the reference cells used to determine the average background level. Unfortunately, the large processing time required by this technique limits its practical use.

WebAug 1, 2024 · The order statistics CFAR (OS-CFAR) proposed by Rohling is the best known robust CFAR detector. It selects the sample with a certain order after a value rank-ordered process as the estimate of the local clutter level [5]. OS-CFAR exhibits reduced sensitivity to spurious targets in reference cells but the CFAR loss will increase in a homogeneous ... WebDetection performances for optimal, CA TM, CA, trimmed-mean (TM) and ordered-statistic (OS) CFAR strategies have been analyzed and compared for desired probability of false alarm and determined size of the reference window. False alarm rate performance of these processors has been evaluated for different strengths of interfering signal and the ...
