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。(INSAR (Interferometric Synthetic Aperture Radar) is a new technology of space-to-Earth observation, in which two SAR images in the same area are used as basic processing data. The phase difference between two SAR images is calculated to obtain the interferometric image, and then the terrain elevation data is obtained from the interferometric fringes by phase unwrapping.)

一个VB图像浏览缩放控件，支持浮动图片缩放按钮、鼠标拖动、滚动条移动等功能，适时显示鼠标定位点在图片上的位置，基本上图片预览的功能都具备了，直接添加到工程中使用，编程方便灵活。
