Abstract
Based on the GF-3 satellite sliding spotlight imaging model and echo signal characteris-tics,according to the characteristics of the sliding spotlight meter level high resolution and highly sensitive to echo signal error,SAR focusing on the sliding spotlight high-resolution imaging algo-rithm into the deep research,this paper presents a combination of internal calibration signal am-plitude and phase error compensation of the sliding spotlight high resolution DCS imaging algo-rithm,and presents the algorithm detailed implementation steps and technical process.The measured data by using the high GF-3 satellite is processed to verify the effectiveness,the results show that the combination of internal calibration signal amplitude and phase error compensation of DCS imaging algorithm can effectively improve the image quality of sliding spotlight high-resolution SAR imaging,and imaging processing can be obtained better focusing effect and algo-rithm than traditional methods.关键词
