Dim target detection of high speed moving radar in complex electromagnetic environment

Abstract

In order to detect the faint and small targets in the high-speed moving radar in the complex electromagnetic environment, a new method for tracking the faint and small targets in the complex electromagnetic environment is proposed. First of all, pre-processing and dynamic planning of the radar image sequence. Multi-stage hypothesis testing is performed on the candidate trajectories after frame accumulation. After the target trajectory is judged, the trajectory is tracked to realize the detection of faint small targets. Experimental results show that the proposed method can effectively improve the detection performance of small and dim targets, and it takes less time, with a minimum time consumption of 16.7s.
