Radar ECCM against deception jamming: A novel approach using bi-static and mono-static radars

Abstract

Bi-static radars have started to regain some recent attention over the past decade because of its abilities to counter deception jamming. This paper aims at utilizing the merits of bi-static radars that is used in combination with a mono-static radar. The proposed scheme counters the effects of range gate pull off (RGPO) and velocity gate pull off (VGPO) which are the two prime deception methods against modern radar systems. These methods are becoming ever increasing threats to ground based radars in modern era due to the advancements in digital radio frequency memory (DRFM). By using a combination of mono-static and bi-static radars in a simple yet effective configuration, it is shown that range deception and velocity deception jamming can be identified and the target can be localized.
