基于对比度的雷达景象匹配可靠性研究

传统的分析景象匹配可靠性是通过研究匹配信噪比、独立像元数、参与匹配的像元数来进行的,但对于雷达景象由于其特殊的图像特性,传统的方法往往得不出正确的可靠性分析结果。从搜索图的对比度来研究景象匹配可靠性问题,根据匹配过程中的特点,第一次从理论上推导出了对比度和匹配可靠性的定量关系,通过大量实践表明,运用对比度来分析雷达景象匹配的可靠性是一种十分有效的方法。

Reliability Research on Radar Scene Matching Based on Gray Scale Contrast

It is traditional method to research on reliability of scene matching by means of analyzing SNR,Independent Pixels,Total pixels participating in the matching,But the traditional means can not draw out the correct result for the Radar image owing to the characteristics of the image.The article analyzes the matching reliability by researching on the contrast of gray scale of radar image and the character of matching process.For the first time the article gets the fix quantity relation between the contrast and the matching reliability.It is proved by a great deal of experimentation that the method based on contrast of gray scale is an effective way to analyze the reliability of scene matching of radar image.
