Abstract This paper presents the practical spaceborne synthetic aperture radar (SAR) data focusing method based on the realistic end-to-end spaceborne SAR simulation. Our simulation reflects main factors of the satellite SAR that induce errors to degrade the focused image severely, which are related to the sensor hardware, the antenna beam pointing, the effective velocity, and the Doppler frequency. To minimize errors due to them in the spaceborne SAR image formation, we suggest and utilize the…
