A fast method for spaceborne SAR image formation based on HLA

In order to achieve efficient parallel processing of the spaceborne Synthetic Aperture Radar (SAR), this paper studied the principle and flow of a compatible algorithm for imaging of spaceborne SAR based on the HLA and designed the framework of imaging system as well as the simulation of each federate. As a following, it also analyzed the method how to attain parallel processing. Furthermore, the mode of data transfer among federates was proposed. Finally, the simulation results justified the effectiveness of the method.
