Abstract

The Pareto distribution has been validated as a new clutter intensity model for X-band high resolution maritime surveillance radar returns. Consequently, corresponding detection schemes have become of much interest. This paper examines the development of constant false alarm rate radar (CFAR) detectors operating in Pareto distributed clutter. Recent developments in the literature have shown that it is possible to produce CFAR detectors for this clutter model by transforming the Gaussian intensity CFAR detectors. This results in the preservation of the Gaussian threshold multiplier/probability of false alarm relationship. The cost of doing this is that the new CFAR process depends on the Pareto clutter scale parameter. This paper examines an alternative approach to Pareto CFAR development.
