基于双/多基 SAR 的集群协同探测与制导新进展

In complex environments such as high dynamics，strong confrontation，and limited resources，the collab- orative detection and guidance technologies of cluster combat systems face severe challenges. The collaborative de- tection and guidance technologies based on bi/multi-static Synthetic Aperture Radar（SAR）can achieve passive for- ward looking high-resolution wide-range imaging，multi-view information fusion enhancement，and multi-directional col- laborative strike，and is thus an effective solution to the problems of highly reliable collaborative detection and guidance of clusters and completion of the closed-loop of Observation-Orientation-Decision-Action（OODA）loop in complex en- vironments in the future. In recent years，with the advancement of bi/multi-static SAR technology，there has been sig- nificant development in the research on using bi/multi-static SAR in collaborative detection and guidance. This paper aims to review the research progress of bi/multi-static SAR in cluster collaborative detection and guidance. Firstly，the mechanism and typical working modes of collaborative detection and guidance based on bi/multi-static SAR are re- viewed，and the technical requirements for the two core key tasks of collaborative detection and guidance based on bi/ multi-static SAR in complex environments are sorted out. Furthermore，the key technologies and their progress in- volved in collaborative detection and guidance based on bi/multi-static SAR in complex environments are introduced，and the bottlenecks and challenges of collaborative detection and guidance technology based on the bi/multi-static SAR are analyzed. Finally，considering the challenges such as intelligentization and anti-interference，the future devel- opment trend of cluster collaborative detection and guidance technology based on bi/multi-static SAR is also discussed.
