| 摘 要： | 在复杂地形条件下,SAR影像几何失真大,辐射畸变突出,透视收缩、叠掩和阴影等现象严重,制约SAR测图的应用.为此,提出一套基于多方向多源SAR数据融合方法与技术流程,利用不同侧视方向、不同分辨率、多极化的SAR影像数据,融合制作信息量丰富,能够满足应用要求的SAR假彩色正射影像.采用横断山脉区域3 m分辨率的Terra...

| Abstract: | SAR images acquired from some complex terrain areas present serious geometric distortions.Foreshortening,layover and shadow are usually extremely severe.The radiometric distortion induced by topographic relief is also strong.These factors limit the application of SAR mapping.Therefore,a new method and technical flow based on multi-direction and multi-polarization SAR data fusion was proposed according to complex terrain and inherent characteristics of SAR images.This method fused SAR images acquired from di... |
