- A novel high-order imaging algorithm for high-resolution spaceborne synthetic aperture radar (SAR) is presented. First, an equivalent squint range model is developed by considering the radar acceleration effect; second, a high-order imaging algorithm is derived by solving the insufficient pulse-repetition frequency problem through an improved sub-aperture method. Extensive analysis and simulation show that accurate focusing is achieved using an extended hybrid correlation algorithm. The solution enables satellite manufacturers to construct a precise range model and to implement an efficient imaging algorithm.
