A new shift pulse compression method for multiple targets' detection

The detection of multiple targets is always a difficult problem in radar. The core point is that the multiple targets cover each other, which makes it difficult to detect small targets. In order to solve above problem, a new detection method for multiple targets based on shift pulse compression (shift PC) is proposed in this paper. The idea of sum-difference amplitude ratio is used to suppress mutual masking problem caused by main broadening of multiple targets, where the difference channel is constructed by shift PC of left and right with each half range cell. The experimental results for the detection of multiple targets show that the proposed method can improve 20% the detection probability of small targets among multiple targets when the false alarm rate is 10 ⁻⁵ .
