Abstract :
This paper presents the theory of dual-channel receiving Synthetic Aperture Radar (SAR) and internal calibration. Using the data of an airborne high resolution SAR demonstrate System collected in May 2006, the internal calibration error and amplitude & phase errors are analyzed. The raw data is compensated by internal calibration data to improve range compression quality compared to auto-focus method compensation. The image of synthesized dual channel data is performed. With the internal calibration and the dual-channel amplitude & initial phase errors compensation, the quality of SAR image can be improved dramatically.
