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 ...

WebJul 20, 1998 · In this CFAR, the returns in the reference set are ordered by increasing magnitude and the Kth largest such order statistic is used to set the threshold. In a reference set of size L samples, this has the effect of allowing up to L − K interfering targets to be present before serious degradation in detectability occurs.
