A Study on Relationship Between Smart Noise Jamming and SLB

The statement about concept of smart noise jamming is oppugned in this paper.Based on matching filter theory,essential signification of smart noise jamming is analysed.And than,relationship between smart noise jamming and SLB is discussed.It is pointed out that smart noise jamming have no effect on function of eliminating side-lobe jamming of SLB;for utilizing SLB to block a radar,using smart noise jamming can reduce request for jamming power in a certain degree but have no effect on request for jamming power from difference between the main antenna gain and the assistant antenna gain;for answering smart noise jamming,the radar ought to further reduce side-lobe of main antenna to increase difference of the main antenna gain from the assistant antenna gain and make it more difficult to block a radar by smart noise jamming.
