Abstract:During the mapping task using high-resolution airborne SAR images, the effective using of DGPS data has important influence on the final accuracy and efficiency of surveying and mapping. This paper analyzed the imaging geometric characteristics of airborne SAR system, and, under the condition of space-constant PRF imaging technique, it put forward to a kind of flight track processing method for radar sensor position correction using iteration computation supported by DGPS data. And further, it discussed the da… Show more
