Virtual polarization makes variable polarization reception change from simula- tion end to digital side, in a fast, accurate and flexible way. If apply virtual polarization filter to the radar receiver system, it will significantly enhance radar＇s capability of clutter sup- pression and target detection, improve radar＇s viability in harsh battlefield environment. On the basis of analyzing the virtual polarization theory, extracts the polarization parameters by using correlation matrix recursive estimation, and proves that virtual polarization filter will improve effectiveness of radar receiver performance by the simulation.
