On the Processing of Very High Resolution Spaceborne SAR Data: A Chirp-Modulated Back Projection Approach

A new image formation algorithm is proposed for processing very high resolution spaceborne sliding-spotlight synthetic aperture radar (SAR) data. Because of along-track antenna steering, the Doppler bandwidth of the received SAR data is expanded significantly beyond one pulse repetition frequency in...
