A Method for PD Radar Dim Target Detection Based on Stochastic Resonance Principle

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.Firstly,the basic principle 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 res...
