A polarization filtering method based on oblique projection operator

Combining polarization filtering with the oblique projection, we address an oblique projection polarization filter (OPPF) which enables the extraction of the desired polarized waves while suppressing the unwanted polarized interference signals, based on estimating the polarized parameters subspaces of desired signals and interferences. The simulation results show that the OPPF is a valid means to remove the interferences in polarization field.
