Abstract

A method of satellite operation utilizing a paired-satellite configuration in which one satellite illuminates the imaged field of view and the other satellite receives the reflected energy using bistatic synthetic radar. This method enables the unambiguous detection of radar signals for imagery construction, improves stability for image quality, provides recording format linearity to minimize image reconstruction processing, provides orthogonal range-doppler pattern distribution at all points in the recording plane to minimize computer processing, provides a triangulated signal reference baseline to improve system calibratability, and enables conformal mapping and uniform sampling of zone plates to achieve three dimensional holography.
