Abstract
A novel main-lobe blanketing interference suppression method which named as spatial virtual multiple channel concurrent polarization filter technology is proposed. It processes sample data using the slow varied polarization property of a scanning antenna. The orthogonal polarized signal and polarization states of the receiving signal can be obtained. The optimal polarization is then calculated for use in polarization filtering to achieve the objective of suppressing noise jamming. The effect of elevation measurement error on interference suppression performance is eliminated by concurrent processing. Theoretical and simulation results show that, this technology enabled self-polarization information processing for single polarized radar which improved its working performance.
