摘要
Abstract
A smart jamming method for synthetic aperture radar(SAR)multiple targets based on noise convolutional modulation is proposed to address the shortcomings of traditional noise convolutional jamming that the position of the suppression area can't be flexibly controlled in the azimuth direction.This method performs range frequency shift,azimuth phase shift,and convolutional modulation with noise templates on the intercepted signal to control the position of the suppression area.The intercepted signal is subjected to noise convolutional modulation with different frequencies and phase to control the number of suppression areas.Theoretical and simulation results show that the proposed method achieves flexible control of the position of the suppressed area in the azimuth and range directions,and achieves jamming from a single jammer to multiple areas to be covered,improving jamming gain and achieving great jamming effects.It has certain reference value for practical engineering applications.关键词
