Abstract

Abstract

A new detection scheme based on Hough transform for spatially distributed moving target which range walks and has strong range cells is proposed. The proposed scheme, Hough Detector (HD), consists of two steps. In the first step, a primary threshold is set and any range-time cell of High Resolution Range Profiles (HRRPs) with a value exceeding this threshold is mapped into Hough parameter space and then every Hough cell is refined using its own Cumulative Distribution Function (CDF). In the second step, summations of several strongest cells of every angle in Hough space are calculated, then the summations is mapped by their own CDF. The maximum of the mapped summations is used as the test statistic for target detection. Experimental results for measured data of three planes illustrate that Hough detector achieves at least 1.3 dB improvement comparing with the existing Scatter Density Dependent Generalized Likelihood Rate Test (SDD-GLRT).
