ALR detector comparison with the Hough detector in a search radar

Abstract

In this paper, the disadvantages of using the Hough transform as a detector have been considered in a search radar. To illustrate the effect of these disadvantages on the performance of the detector, its performance has been compared with the optimum detectors. To do this, the Average Likelihood Ratio detector has been extracted for detecting a target line with a known normal parameter pair in the search environment. Then, the performance of this detector has been compared with the Hough detector by extracting their Receiver Operation Characteristics. The results of this comparison, which has been done through simulations, show that the Average Likelihood Ratio detector has a better performance.
