CFAR detection in heterogeneous K-distributed sea-clutter background [PDF]
Detection of targets at sea is challenging due to unwanted echo returns from the sea surface, i.e. sea clutter returns. To account for the undesired effects due to sea clutter at the receiver, and to control the probability of detection and false alarm ...
