Abstract :
Based on the oblique projection operators, a novel method for interference suppressing named oblique projection polarization filter (OPPF) in the polarization domain is proposed, which is valid for nonorthogonal polarization filtering or projecting. After discussing the fundamental principle of the proposed OPPF in detail, simulation results are given to illustrate the suggested scheme is suitable for canceling the interference in radar and other systems even if the polarizations between the target signal and interference are not exactly orthogonal.
