Abstract The SAR working mode of range multi-aperture is a high resolution imaging mode for wide swath. Resolving and imaging are the two parts of range multi-aperture imaging algorithm. How to match the two parts together is the key problem for the algorithm. This paper presents a new method based on SCFT (SCaled FT) to solve the problem. Simulation and comparison between different methods is also given to prove the feasibility of range multi-aperture SAR imaging method based on SCFT.
