A Study on Internal Calibration Technique for Airborne Super-resolution SAR
摘要
Abstract
Firstly, principles of internal calibration technique are introduced in airborne synthetic aperture radar ( SAR) , and the real-time transmission signal data of SAR send calibration is analysed.Then, the performance indicators of one dimensional range image are given with and without the systematic errors compensation, meanwhile, a method is proposed using the real-time calibration data as reference functions in SAR image processing.Finally, the successful radar flight test and the high resolution range profiles have proved the feasibility of this method.关键词
