Abstract
This paper introduces four kinds of error equations about 3D GCPs,plain GCPs,elevation GCPs and pass points based on polynomial ortho-rectification of SAR images;and then a block adjustment model of SAR images is given.According to this model,program has been designed and experiment has been done on airborne SAR images of study site in Chengdu.The experimental results are feasible.
