【Abstract】 A polarimetric adaptive matched filter with the coherent radar against a gaussian background is presented. Previously proposed single chanel and double channel adaptive matched filters are extended to the case of a general number of channels. The expressions of PFA for AMF a general number of chanels are derived. It is shown that the proposed detector has the const false alarm properties with respect to the covariance matrix of the clutter. We resort to simulation to analyze the performance in different polarimetric cases.更多还原
