• blanketing jamming
• suppression
• spatial polarization characteristic

Blanketing jamming is widely used in electronic jamming war, whereas the existing electronic countermeasures maybe invalided in the future. By using the spatial polarization characteristic (SPC) modulation effect on jamming signal as antenna scanning, a novel side-lobe blanketing jamming suppression method is proposed. It processed the sample data by using pre-knowledge of jamming direction, SPC, then the orthogonal polarized component and polarization states of receiving signal can be estimated. The polarization filtering is designed to achieve the objective of suppressing jamming. The novel method enables single polarized radar own anti-jamming ability in polarization domain, where the suppression performance can reach to 20 dB. The validity has been proved by simulation experiment.
