Abstract:

In the presence of the difficulty of monopulse radar track deception, a netted mainlobe jamming technique is proposed under the background of netted jamming against modern radar. The course and process of the jamming is put forward based on the analysis of the basic theory of monopulse radar jamming and the key point of track deception. Firstly, the coherent jamming is constructed by the transmission path and the phase control of the jamming signal, and the fundamental model of the generation of phantom dots in radar mainlobe is built. Furthermore, the jammer net working mode is designed which emphasizes the cooperation in the jammer group and relay between the jammer groups. Thus, the jamming model is improved on integrating the phantom dots into a full track for long time high-reality deception. Simulation results verify the feasibility and validity of the proposed algorithm.
