Considering the fact that radar could not resist variable polarization interference, a method was proposed to extract interference polarization state by constructing fully polarized auxiliary antenna to realize the polarization cancellation. The reception problem of fast varying polarization interference was analyzed, and the model was established, then the cancellation algorithm of slowly varying polarization interference was derived theoretically. The simulation results showed that the proposed algorithm could achieve good effect on slowly varying polarization interference. With the increase of the polarization speed, the jamming effect was similar to the noise suppression interference, so it could not extract the polarization state of the interference accurately, and it was difficult to realize the cancellation.
