中文说明：
合成孔径雷达干涉测量技术（INSAR，Interferometric Synthetic Aperture Radar；简称：干涉雷达测量）是以同一地区的两张SAR图像为基本处理数据，通过求取两幅SAR图像的相位差，获取干涉图像，然后经相位解缠，从干涉条纹中获取地形高程数据的空间对地观测新技术。
English Description：
Synthetic aperture radar (InSAR); Interferometric Radar Measurement) is a new spatial earth observation technology that takes two SAR images in the same area as the basic processing data, obtains the interferometric image by calculating the phase difference of the two SAR images, and then obtains the terrain elevation data from the interferometric fringe through phase unwrapping
