Algorithm for the Latitude and longitude of an Arbitrary Pixel in Air-borne Strip Mode SAR Image

摘要

As there are lots of advantages, synthetic aperture imagery is widely applied. Effective utilization of synthetic aperture imagery often requires precise latitude and longitude of each image pixel. In the case that the side-glance angle of beam is zero or small, a new algorithm has been developed to determine the latitude and longitude of an arbitrary pixel in an airborne strip mode SAR image without consideration of the hypsography. The algorithm is precise and applicable. Error analysis of the algorithm is also made based on the parameters of a practical radar in the paper.
