Chapter 25 Multiple Moving Targets Detection Based on Hough Transform and Matched Filter

摘要

The most fundamental problem in radar signal is detection of a moving object or a physical phenomenon. This problem became more challenging to the signal processing and radar communities to detect multiple moving targets under severe interference. In order to effectively detect moving targets in strong noise conditions, we proposed a new method based on matched filter and Hough transform (HT) for multiple moving targets detection. At first, the noise is removed from the received signal by the matched filter with a cross correlation technique. Then, the image processing technique of the Hough transform is used. The benefits of this method include improved performance of detection, implementation flexibility, which indicates the effectiveness and robustness of the algorithm.
