【摘要】 在用InSAR技术进行地表变形检测时,往往存在一些因素影响着检测精度,解决该问题很重要的一个途径是设置人工角反射器,或者引进所谓散射体的概念。而要利用角反射器,就必须研究角反射器检测技术。本文根据SAR图像角反射器的特点并结合模式匹配方法,提出了一种有效的SAR图像角反射器点检测方法,实验结果表明该角反射器点检测方法是有效的。更多还原

【Abstract】 InSAR(Synthetic aperture radar interferometry) technique has been used widely to examine deformation of the earth’s surface,however,there are often some factors of affecting examination accuracy.One of the good ways of solving the upper problems is to put up artifical corner reflectors,or to introduce concept of scatterers.However,to use corner reflectors,corner reflector detection method must be studied.In the paper, based on the characteristic of SAR image corner reflectors,also with pattern matching method,an efficient method of corner reflector detection for SAR Image is proposed.The experiment results show that the new method of corner reflector detection is efficient.更多还原
