Research on a New Comprehensive CFAR (Comp-CFAR) Processing Method
IEEE Access, 2019 Since the clutter statistics of marine radar are non-stationary and difficult to ascertain, the constant false-alarm rate (CFAR) processor based on some clutter statistical characteristics is hard to obtain the CFAR performance.
