The application of adaptive three-dimension polarization filtering in sidelobe canceller

摘要

To improve the performance of the sidelobe canceller, a method using adaptive three-dimension polarization filter is proposed to suppress the target signal in the auxiliary antenna. It uses three orthogonally polarization channels in the auxiliary antenna, Through the adaptive polarization filtering adjusting the receiving polarization vector of antenna to be orthogonal with that of the target signal, the target portion can be suppressed possibly, and the interference portion can be retained. then the output signal can be obtained by adopting the algorithm of adaptive sidelobe canceller. At last, the simulation results prove the validity of the method.
