摘要
随着合成孔径雷达(SAR)的应用研究程度的深入,要求较为精确地掌握目标体的雷达后向散射特征,这样必须对SAR图象进行真实值的定标与校验。本文基于基本散射理论对SAR系统的增益进行分解,指出各个相关参数的获取方法。
With the improvement of the utilities of synthetic aperture radar(SAR)imagery,researchers must get acknowledge of accurate radar cross section of the research targets.For this reason,the value of the SAR imagery must be calibrated and validated.This thesis separate the system total gain into parts based on the principle of electromagnetic wave theory and gives each part with its relating reference data and the methods to get the data.And finally,a chart of calibration is given.
