The Design of Parallel Imaging System Based on MNMP Mode

This paper investigates the parallel processing of spaceborne ScanSAR in detail. Firstly, it analyzes the character of ScanSAR imaging and gives the parallel processing flow based on the traditional Host-Slave (HS) mode. Then, a new parallel technology based on Multiple Node-Multiple Progress (MNMP) mode is proposed, it can improve the deficiency of HS mode. The simulation result indicates the parallel processing based on MNMP mode improves the imaging time. So the way is feasible and superiority.
