“…Some heavy-tailed radar clutter models, such as K distribution [16][17][18], Pareto distribution [19,20], KK distribution [21,22], are utilized in the target detection scheme design. In [16], the K-distribution is expressed as spherically invariant random process and then two CFAR detectors, i.e., scatterer density dependent GLRT (SDD-GLRT) and non-scatterer density dependent GLRT (NSDD-GLRT), are proposed.…”
