1. A method, comprising: determining, by a processor of an airborne device, geographic coordinates of corresponding pixels of a target from first and second digital synthetic aperture radar (SAR) images by capturing, by the processor of the airborne device, the first and second SAR images in a form of slant range images; determining, by the processor of the airborne device, a recording position of the respective first and second SAR images; determining, by the processor of the airborne device, a distance between a corresponding resolution cell on a ground and the respective recording position of the respective first and second SAR images using coordinates of the corresponding pixels of the target in the first and second SAR images and corresponding range gates; and determining, by the processor of the airborne device using the determined distances and associated recording positions of the first and second SAR images, the geographic coordinates of the corresponding pixels of the target in the first and second SAR images by producing, by the processor of the airborne device, a first and second sphere for the first and second SAR images using the determined distances and associated recording positions of the first and second SAR images; and determining, by the processor of the airborne device, the geographic coordinates of the corresponding pixels of the target as a common intersection of the first and second spheres with the WGS84 ellipsoid.
