Study of Three Non-Coherent Integration Techniques for Multiple-Pulses Trimmed-Mean CF AR Detector

The Pareto distribution has recently been validated as an appropriate model of the clutter echoes specific to X-band high-resolution maritime surveillance radar. As single-pulse and multiple-pulses Constant False Alarm Rate (CFAR) detectors operating in homogeneous and non- homogeneous Pareto clutter have been proposed in the radar literature, with the aim of improving the detection performances, this paper focuses on the analysis and the comparison of the performances of three non-coherent techniques for the multiple-pulses Trimmed-Mean (TM-) CFAR detector with unknown parameters. We cite the TM Conventional (TMC-) CFAR detector, the TM Non- Conventional (TMNC- CFAR detector and the TM Binary (TMB-) CFAR detector. In doing this, we evaluate and compare the detection performances of these techniques through Monte Carlo simulations for Swerling I (SWI) and II (SWII) targets, in homogeneous clutter, clutter edge and/or multiple target situations. Due to its good regulation of the probability of false alarm, the TMC-CFAR detector shows the best performances.
