%X This paper proposes a compression method for Synthetic Aperture Radar (SAR) raw data,which is based on time-frequency analysis theory and the linear frequency modulation properties of the SAR raw data. In this method, the raw data of I and Q channels is divided into blocks at first, then each block is transformed into time-frequency domain by 2D-RDGT (Two-Dimensional Real valued Discrete Gabor Transform) and the desired bits are allocated to each frequency plane, finally each frequency plane is quantized wi...
