Geo-Location Error Correction Using Sensor Parameters Eztracted from Spaceborne SAR Raw Data

摘要：

Spaceborne SAR imagery inherently contains the errors from the ground range nonlinearity and earth rotation. The fusion of SAR image and GIS information may enhance the SAR image quality by correcting the geometric error which is induced from the geolocation and terrain error.In this paper,a geolocation error correction method is proposed. This scheme does not require the aids of GCP and DEM,and instead directly extract the key correction parameters from the SAR raw data. The simulation results using Radarsat-1 SAR image shows good performance in correcting a geo-location error without aid of auxiliary data.
