摘要：
This paper introduces a hybrid imaging mode of spaceborne SAR, which holds the particular advantages of high-resolution and large imaging swath, and it has been uniquely applied to the TECSAR Satellite of Israel successfully in 2008. According to the azimuthal time-frequency analysis of mosaic mode, imaging method is presented and ECS algorithm is selected for processing a single mosaic data. In order to resolve the inevitable Doppler ambiguity, a data preprocessing algorithm is utilized to improve the traditional ECS algorithm. Finally, simulation results demonstrate the validity of the proposed imaging method.
