A Method for Suppressing Convolution Modulation Jamming of LFM Fuze
摘要
Abstract
As the smart jamming signal toward pulse compression receiver,convolution modulation jamming sig-nal can effectively jam linear frequency modulated(LFM)fuze in pulse deceiving . Firstly,to make the LFM fuze suppress convolution jamming effectively,mathematical model of convolution jamming and the convolution jam-ming mechanism is analyzed . Then orthogonality relations between the jam signal and the fuze echo signal is es-tablished by mathematical theory . The orthogonal projection,which can suppress the convolution jamming,is established . Finally,taking the LFM signal as example,orthogonal projection can effectively suppress the de-ceiving jamming signal based on convolution modulation,which is analyzed by simulation . The study shows that orthogonal projection achieves the effect of suppressing the multi-false-target in pulse deceiving.关键词
