A new technology is studied in this paper, which uses the virtual polarization filtering to suppress the angle cheating interference. For the amplitude sun/difference mono-pulse radar, the reception model of full polarization signals is established and the polarization filtering is finished by digital technology in the signal processor. The effectiveness of polarization filtering is discussed.The polarization parameter estimation method is given and the effect of the estimation error on the polarization filtering and angle measurement is analyzed. The research results indicate that virtual polarezation filtering technology can suppress the angle cheating interference effectively and improve the guidance precision notably.
