Study on the angle glint suppression technology for high resolution dual polarization radar seeker

For the high resolution dual polarization guidance radar, a new glint suppression technology is proposed in this paper. The technology can notably ameliorate the angle measurement precision and improve the anti-jamming ability of the radar. The basic idea is that the effective scattering centers in radius of the extended target are separated based on the twice detection of amplitude and polarization in order to eliminate the effect of interference scattering centers firstly, then the angles of each effective scattering centers are measured according to mono-pulse method, finally the average geometer position of the target is determined by weighting the measured angles of the effective scattering centers and tracking reliability of the target is realized. The signal model and specific angle glint suppression algorithm are given, and the effectiveness of the algorithm is testified by simulation.
