Fast Hough transform algorithm for radar detection

In this paper, a fast algorithm for radar detection based on line Hough transform is presented. Unlike the traditional method, the idea of our proposed is that the point of data space should be mapped into the Hough parameter space of slope and intercept, where the relative position of the points in the data space is preserved. Then, only one time transformation of coordinate is employed to get the position of a batch points in parameter space. Therefore, the computation burden is significantly reduced. In addition, the detector performance is investigated. Finally, we illuminate the reduction of computation in details.
