Design and simulation verification of spaceborne AIS guiding SAR imaging algorithm

How to quickly and effectively monitor a specific target ship in the imaging area of spaceborne SAR is a research hotspot of ocean surveillance techniques which based on the fusion of spaceborne SAR and AIS information. This paper proposes a spaceborne AIS data preprocessing algorithm for guiding SAR imaging, briefly introduces the application scenario of the algorithm, and introduces the algorithm processing flow in detail. Finally, a simulation test system is built to verify the feasibility of the algorithm processing flow. The experimental results of the simulation system show that the algorithm can assist the fast matching and searching calculation of specific target ships in the SAR imaging area, improve the SAR payload target recognition efficiency ratio, and improve the real-time data processing capability of spaceborne SAR payload.
