一种基于随机共振的PD雷达小目标检测方法
A Method for PD Radar Dim Target Detection Based on Stochastic Resonance Principle
摘要
Abstract
Dim signal detection is chanllenging due to the fact that the signal is submerged by the powerful sidelobe clutter, while the pulse Dopple ( PD) radar is following the target. Stochastic resonance principle is made good use of to improve the signal noise ratio and the detection performance. Firatly, the basic pnnciple of stochastic resonance is introduced, and the frequency spectrum characteristic of the return signals is analyzed while the radar is after the target. Then a novel approach based upon stochastic resonance principle for detecting a single dim signal of pulse Doppler radar is proposed, and the procedure is given in the paper. The performance of signal noise ratio improvement is thus analyzed theoretically. Finally, the simulation results show that the proposed algorithm possesses a high gain for siganl noise ratio, which is very attractive for dim sigal detection of pulse Doppler radar.关键词
