Satellite configuration for interferometric and / or tomographic mapping the earth's surface by means of synthetic aperture radar (SAR)

For interferometric and / or tomographic mapping the earth's surface by means of synthetic aperture radar (SAR), which form one to N receiver satellites and / or transmitting satellite and / or transmit / receive satellite with a horizontal across-track shift, and with the same or different amplitude a satellite configuration , Here, the satellites are in the same orbit height and moving at the same speed on circular orbits. Further, a horizontal along-track distance between the individual receiver satellites is adjustable, which is independent of the orbit position constant. DOLLAR A Here, one or more receiver satellites in the same orbit height at the same speed on a circular orbit having a varying over the orbit circulation horizontal across-track shift is provided in such a manner that the maximum of the horizontal across-track shift for each satellite via another is latitude, and the maxima of the horizontal across-track shift are positioned so that the baselines are maximized for across-track interferometry. A transmitting or transmitting / receiving satellite is either positioned separately from the configuration without across-track shift, or as a part of the configuration with a horizontal across-track shift.
