Abstract A simple polarimetric CFAR detector for coherent radar against a Gaussian background is presented. The expression of PFA for the detector is derived. It is shown that the proposed detector has the constant false alarm properties with respect to the covariance matrix of the clutter. With respect to the polarimetric generalized likelihood ratio test detector, the proposed one has less complexity. It is appropriate to high SCR and unknown steering, vector case. The performance in different polarimetric cases is analyzed.
