摘要: 從全極化(hh,hv,vh,vv)合成孔徑雷達(dá)(SAR)圖像數(shù)據(jù)中,可提取方位向的地勢(shì)傾斜度信息,形成極化SAR三維成像。該文重點(diǎn)研究極化 SAR三維成像快速算法;提出由 Stokes矢量推導(dǎo)的的極化橢圓方向用解模糊算法;討論目標(biāo)極化散射特性對(duì)提取地勢(shì)高度信息的影響以及處理方法;并利用真實(shí)的極化 SAR圖像數(shù)據(jù)得到了極化三維成像結(jié)果。Abstract: Terrain slope information may be drawn from polarimetric synthetic aperture radar (SAR) two-dimensional image, so that three-dimensional image can be generated. The image data to algorithm discussed in the paper is a key technique to process polarimetric SAR image data to extract terrain slope. The solution fuzzy algorithm of the polarimetric ellipse rotation angle has been proffered and proved in the paper. The target scatter cross-section or signature-peak in the co-polarization signature generates effect of drawing true terrain slope information. Finally, the paper shows the polarimetric SAR three dimensional images from authentic data.
