Abstract

Abstract:

Mainlobe suppression jamming is a difficult issue in the current radar field. Polarization cancellation is an effective method to anti-mainlobe suppression jamming. Research on the algorithm is conducted for suppressing mainlobe single-polarization jamming cancellation based on simultaneous full polarization multiple-input multiple-output radar. The amplitude and phase estimation algorithm is used to estimate the polarization parameters of single-polarization suppression jamming and the polarization cancellation coefficients. A full polarization multi-channel fusion detection algorithm under suppression jamming is designed. Simulation results show that, given the polarization response of the full polarization array and single-polarization suppression jamming, the power suppression of the jamming signal can reach ?60 dB, and the detection performance after fusion approaches that of the situation without jamming suppression, proving the effectiveness of the proposed algorithm.

Key words: polarization radar, mainlobe jamming, target detection, anti-jamming, parameter estimation
