Abstract：The active repeater jamming is a very important jamming technique in the modern warfare, especially for the air defense, anti-missile and anti-warship operations. It becomes a serious threat for the modern radar systems. This paper focuses on the representative distance-deception and angle-deception artifacts in radar formed by the active repeater jamming techniques. The discrimination and suppression of such active repeater jamming with fully polarimetric mono-pulse radar is studied. The theoretical investigations and simulation experiments demonstrate and validate that the utilization of polarization information has the capability to identify and suppress these jamming patterns. The obtained conclusion shows great potential for the further studies and can assist the investigation of the issue that how radar can be adapted to the complex electromagnetic environment.
