The locally optimum detectors in clutter characterized as SIRP

The high resolution radar is plagued by target-like “spikes” that give rise to non-Gaussian observation and much higher false alarm rate than that of system can tolerate. Several models have been presented to characterize the clutter, and the more attractive one maybe is spherically invariant random process (SIRP). The paper discusses the locally optimum detectors against clutter characterized as SIRP for coherent pulse train with known and unknown initial phase and non-coherent pulse train, which have simple and elegant structure. The performances of three detectors are analyzed in the paper
