摘要：
The performances of the cell-averaging (CA) and order-statistic (OS) CFAR detectors processing M correlated sweeps are analysed for the case where one or more interfering target returns are present in the set of reference cells used in estimating the clutter-plus-noise level. Exact expressions are derived for the detection probabilities of these schemes under Rayleigh fluctuating target model. The OS-CFAR performance for that case gives an integral equation which is evaluated numerically. Performances when sweeps are independent can be obtained easily as a special case.
