Abstract:

A cooperative suppress jamming method uniting multi-false target and smart noise for the linear frequency modulation pulsed radar with the mean level constant false alarm ratio detector is proposed. Firstly,the proposed method is illuminated about how it takes advantage of the convolution modulation to realize the distribution of multiple false targets. After that several key parameters such as the number of the false targets and the signalnoise ratio are derived. Due to the poor performance of the multiple false targets under the condition of deviations exist in measured values,noise jamming is proposed to promote the effect of cooperative jamming, and then the required power of noise is calculated. Finally,simulations are made to validate the effect. Simulation results show that the cooperative jamming can reduce the detection probability of radars greatly and the detector of the radar is jammed effectively.
