Radar Detection Performance in Medium Grazing Angle X-band Sea-clutter

Abstract

This report describes the target detection performance of an airborne surface surveillance radar in the presence of medium grazing angle sea-clutter. In the absence of frequency agility, the temporal correlation of the sea-clutter can be significant and if it is not accounted for in the radar model, the required signal to interference ratio for a given probability of detection, P(sub d), will be incorrect byseveral dB, resulting in over-estimated performance. This report describes a robust method for calculating the P(sub d) for both K and Pareto compound sea-clutter distributions. Empirical models of the amplitude distribution and the speckle correlation are used to determine the expected detection performance given different collection geometries and environmental conditions with the output used to determine the minimum detectable target radar cross section in a detection scenario.
