In the Wide-field Super High-resolution Spaceborne Multiple-transit and multiple-receive Sliding Spotlight SAR,the line-of-sight approximation of the curved orbit is not established,so traditional imaging algorithms based on line-of-sight approximation is no longer available.For this problem,a super highresolution velocity scaling algorithm(SHRVS)is proposed to meet the need of wide-field and super highresolution.Besides,in the procedure of sub-band assembling,a high level virtual image appears due to the f...
