Ground Clutter Analyses in Noise Radar using Unmatched Filter Concept

Abstract

The ground clutter is one of the limiting factors for efficient target detection in noise radar. Thus, a full understanding of clutter return is vital for designing and exploitation of noise radar. The paper presents an enhanced method for analyzing ground clutter return free from masking effects originating from direct crosstalk or strong clutter return. The paper presents theoretical considerations and analyses of simulated echoes. The method can be applied for clutter analyses in noise based scatterometer, e.g. used for measuring scattering effects and a better understanding of ground clutter effects in noise radars.
