A Method for Improving Positioning Accuracy of SAR Imagery Based on RFM

摘要

With the rapid development of the sensor technology, it become possible for us to acquire SAR remote sensing image in the same region, In this paper a method for improving positioning accuracy of SAR imagery based on RFM are investigated. At the same time it associated with model construction, parameter solution and refinement of RFM model are extensively studied, and its block adjustment method was established. Through the experiment of a few SAR imagery covering some places of hunan region in China The experimental result shows that the positioning accuracy can be greatly improved in the case of absence of ground control points.
