Abstract

Deceptive jamming plays an irreplaceable role in electronic counter measures (ECM) due to its flexibility and high power efficiency. Based on digital channelized receiver, this paper proposes a novel deceptive jamming method for linear frequency modulation (LFM) radar, side lobe jamming, which builds decoy group utilizing filter side lobes. Via adjusting the filter structure properly, this method produces false targets at specific positions. Unlike intermittent sampling repeater jamming (ISRJ) which forms a train of symmetric decoys, side-lobe jamming can generate asymmetric false targets, which is more deceptive. On the other hand, it can produce much more false targets than ISRJ, which has a certain suppressive effect on the radar. The experimental results with simulated data verify the effectiveness of the proposed algorithm.
