Noise filtering for interferometric phase image , is one of key problems in insar imaging 摘要干涉相位图的降噪滤波,是干涉合成孔径雷达成像中必须的步骤之一。
The research uses phase diagram to disclose the whole picture of transitional behavior and saddle point path 相位图技术揭示了转移行为和鞍点路径的完整形态。
This thesis centers around three aspects : 1 . present a new method for removing flat earth effect 本文主要进行了以下方面的研究:提出一种新的干涉相位图去平地效应方法。
2 ) set threshold in stationary wavelet domain to separate edge and noise , estimated wavelet coefficients in texture area to reconstruct the interferogram 3 )在静态小波域设置滤波阈值以区分边缘和噪声,根据map准则来确定信号的小波系数,然后重建干涉相位图。
After investigating statistical property of the interferogram , the problem of interferogram phase denoising filtering is discussed . the filtering can be aimed at not only the complex image , but also the phase image 分析了干涉图相位统计特性,讨论干涉图相位降噪滤波问题,滤波可以针对干涉复图像进行,也可以直接对干涉相位图进行。
3 ) unwrapped interferogram after fringe edge detection using dyadic wavelet and edge linking by active contour model ( snake model ) . 4 ) analyzed the effects of atmospheric factors to insar dem extraction and the turbulent character of atmospheric term 3 )利用二进小波对干涉相位图的条纹边缘进行检测,并用主动轮廓线模型( snake模型)连接条纹边缘,在此基础上对干涉相位图进行解缠。
