Multiple targets detection method based on binary Hough Transform and adaptive time-frequency filtering

When the echo energy of multiple targets of vehicle volume detecting radar diverge greatly, small targets are easily masked by the platform of large targets, it is difficult to detect the all the targets by the Wigner-Hough Transform simultaneously. In this paper, a method based on binary Hough Transform and adaptive time-frequency filtering is proposed, which can avoid the problems of detecting the platform of large targets as well as platform masking of small targets and detect all the targets with different energy at the same time. The experimental results show the method has good performance and high practical value.
