When the compound-Gaussian clutters are cluttered into groups of data with one and the same value of the texture
the homogeneous clutter-clustered model is generalized
and a generalized clutter clustered model is established.Moreover
a generalized likelihood ratio test detector based on the generalized clutter-clustered (GCC-GLRT) is proposed
and the formula relating false alarm probability to detection threshold is deduced.The GCC-GLRT solves the problem that the CC-GLRT is not CFAR in inhomogeneous clutter-clustered background.The simulation results show that the GCC-GLRT can overcome the collapsing loss of the NSDD-GLRT detecting spare scatterers target and improve the detection performance of the detector.
