In [1], the continuous-time continuous-amplitude signal is discretized to reflect the sectorization of the coverage area and the range gating operation, and a generalized likelihood ratio test (GLRT) is applied using a Viterbi-like tracking algorithm.
Clutter rejection with direct detection radar by range gating is not possible as the amplitude terms from each reflection are combined together, see (10) and (11), making the range gating of reflecting surfaces of interest impossible as is clearly seen in Figures 3-7.
