Modified Hough Transform for Detection of Range Distributed Targets in Presence of Clutter in HRR RADARS

In this paper a new method based on Houghtransform is introduced for detection of linear trajectories in adata space. Data space is constructed from returned RADARdata using range, and time information. The constant velocitytarget trajectories appear as straight lines in this space thisinformation is then mapped into a Hough space. In this paper weused a new method based on Hough transform which employsthe slope-intercept parameter space Hough for detection of rangedistributed targets. We also use a low pass filter after Houghtransform to improve performance of detection. The efficiency ofthis new Hough transform method is verified by simulation andshown that it has a better performance. This paper considers theproblem of detecting range distributed targets in the presence ofGaussian and non Gaussian clutter. The performance of Houghtransform-based Detector for range distributed target detectionis analyzed through Monte-Carlo simulation runs.
