Abstract:

In complex environments such as high dynamics, strong confrontation, and limited resources, the collaborative detection and guidance technologies of cluster combat systems face severe challenges. The collaborative detection and guidance technologies based on bi/multi-static Synthetic Aperture Radar (SAR) can achieve passive forward looking high-resolution wide-range imaging, multi-view information fusion enhancement, and multi-directional collaborative 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 environments in the future. In recent years, with the advancement of bi/multi-static SAR technology, there has been significant 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 reviewed, 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 involved 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 development trend of cluster collaborative detection and guidance technology based on bi/multi-static SAR is also discussed.
