Abstract:

Multiple phases sectionalized modulation (MPSM) jamming can generate local blanket jamming effect and protect the target against linear frequency modulation pulse compression radar. However, MPSM jamming has a strong sidelobe, which is not helpful for hidden jamming effect. To solve this problem, MPSM jamming method with low sidelobe based on cosine amplitude weighting is proposed. Based on the idea of time-doma in windowed sidelobe suppression, the jamming signal is produced by dividing the received radar signal into several sections and modulating different phases on each section, then weighting each section according to cosine amplitude. After pulse compression, the jamming method can produce a range-controllable blanket jamming effect and have the characteristics of tow sidelobe. The method can not only protect the target, but also reduce the probability of being detected due to the jamming sidelobe. Theoretical analysis and simulation experiments show the feasibility and effectiveness of the method proposed in this paper.

Key words: multiple phases sectionalized modulation jamming, cosine amplitude weighting, local blanket jamming effect, low sidelobe
