Research on the overall technology of space-based distributed radar sea surface target tracking application
Space-based radar(SBR)has unique advantages in wide-area target surveillance,and it is of great practical significance and special difficulty to realize wide-area sea surface target tracking using SBR.Based on analyzing the effects of special problems such as regional unbalanced coverage,low/ultra-low return visit period and real-time processing in application to sea surface multi-target tracking scene for space-based distributed radar system,the tracking processing mode of inter-satellite relay and the tracking processing framework of rasterization pertinently are put forward,and the corresponding multi-target tracking performance evaluation indicator system is presented.The simulation evaluation results show the superiority of the proposed tracking processing framework of rasterization relative to conventional global processing framework and the rationality of the evaluation index.
