Abstract
A system includes a ground hub and a mobile airborne platform hovering over or close to a coverage area on or near the earth surface. The mobile airborne platform comprises a bistatic radar receiver including an antenna system to capture first radiofrequency signals originated from a first satellite and second radiofrequency signals originated from a second satellite, via direct paths and via reflected paths from the coverage area. The mobile airborne platform transmits the captured first and second radiofrequency signals to a ground hub via a feeder link. The ground hub includes a remote beam forming network to remotely form receiving beams for the antenna system of the bistatic radar receiver to capture the first and second radiofrequency signals, and a remote radar processing center to transform the captured first and second radiofrequency signals into a first and a second two-dimensional radiofrequency image, respectively.
