摘要

本文对多尺度合成孔径雷达(IFSAR)的概念、技术和应用作了较为全面的阐述。首先给出了利用简单几何条件推导出的相位干涉法获取高度的基本方程。随后介绍了各种成像方法。最后研究了海拔高度对雷达相位信号的影响。随后，相位差是提取地球数值模型的必要条件。随后研究了这种情况的影响。在干涉测量中，用数值方法计算相位差。最后，本文总结了编制IFSAR高度图的基本步骤。

Extracting the Earth Numerical Model via Interferomtry Images of Synthetic Aperture Radar

In this paper, the concepts, techniques and application of IFSAR (Inter Frometric Synthetic Aperture Radar) are widely considered. First of all the basic equations of IFSAR are presented for obtaining the altitude via measuring phase interferometric which is derived from simple geometric conditions. Afterwards, various Imaging methods were introduced. Finally the effect of altitude on radar phase signal was studied. Subsequently Phase difference is necessary for extracting the earth numerical model. The affect of this condition is studied thereafter. Phase difference is computed numerically in interferometric. Eventually our paper concluded by representing the essential steps for preparing the altitude map of IFSAR.
