Abstract: Using digital radio frequency memory(DRFM) technology to realize deception jamming and noise characteristics of smart noise jamming, good effects can not be achieved from the side-lobe blanking and sidelobe cancellation of radar anti-jamming measures. To solve the problem, based on the analysis of working mechanism of modern radar active noise, combining with the target echo track-related technology, a speed drawing-out cheat and convolution modulation combined new type of smart noise jamming signal form is designed, in order to enhance both smart noise jamming effect of deception and noise suppressing jamming and respond to the ability of anti-interference measures. Simulation results verify the effectiveness of the jamming signal form.
