Study on New Jamming Technology of Modern Linear Frequency Modulation Radar

The modern linear frequency modulated radar has the characteristics of strong anti- jamming capability. This paper proposed a new interference method,frequency shift of smart noise jamming,which based on the Digital Radio Frequency Memory( DRFM) technology studies the frequency shift of smart noise jamming on linear frequency modulation radar. The amount of frequency shift is random and irregular. The interference signal of orthogonal modulation with the acquired radar signal can proceed amplitude compensation,successfully pass through the match detection processing system of radar,and simultaneously interfere a lot of target information effectively. Through Matlab to carry out their simulation verification,it shows that frequency shift smart noise jamming signal generated by DRFM technologies,has the advantage of high power utilization,besides it has double interference effects of deception jamming and oppressive jamming.
