Radar detection and track in presence of impulse interference by using the polar hough transform
Ivan G. Garvanov, Christo A. Kabakchiev · 2007
In this paper, the polar Hough transform (PHT) is con- sidered as a track initiator in a track before detect (TBD) sys- tem. The study is performed in the presence of impulse inter- ference. The algorithm under study includes a parametric CFAR detector, which works successfully in conditions of impulse in- terference and uses the polar Hough transform. The proposed Hough detector improves the detection probability in conditions of both Poisson and binominal random impulse flows. The us- age of both CFAR and Hough transforms materially reduces the requirements to the input SNR in conditions of impulse noise. Another important advantage of PHT is that it is stability when the target velocity and azimuth vary in the time.
