正射图像

该方法由图像分割和分类等一系列技术组成，首先用基于区域分割法则对正射校正SPOT图像进行分割，然后把它作为参考用最大似然法分类器和其他一些经验规则对TM图像进行分类。

This method was made up of a series of image segmentation and classification technique . First , the orthograph revised SPOT image was segmented by applying a region-based segmentation algorithm . Based this reference map , TM image was classified using the maximum likelihood classifier and additional empirical rules .

SAR图像模拟技术被广泛应用于SAR系统的设计和验证、SAR图像的正射纠正、雷达图像解译和目标识别等。

SAR ( Synthetic Aperture Radar ) image simulation has been widely applied in designing and testifying SAR system , SAR image ortho-correction , Radar image interpretation and target recognition and so on .

在傅里叶频谱分析器中，当激光正射前焦面的图像时，在其后焦面上形成一个个衍射斑即傅里叶频谱；

In the Fourier Spectral Analyzer the Fourier spectra or the Fraunhofer diffraction patterns of a graph are formed on the back focal plane when a laser beam is directed on the graph lying on the front focal plane ;
