Abstract
Spaceborne bi- and multi-static SAR is an attractive approach to global-scale along-track and across-track interferometry. An efficient realization of such systems may be achieved by a set of low-cost, passive receivers onboard a constellation of microsatellites which simultaneously record the signals trans- mitted from an existing spaceborne radar. In this paper we in- troduce several multistatic SAR configurations and present the results of an interferometric performance analysis. This anal- ysis includes errors due to the limited SNR, block adaptive quan- tization, range and azimuth ambiguities, and geometric decor- relation for both flat surfaces and random volumes. Rela- tive height accuracies for three spaceborne configurations with PALSAR, ASAR and TerraSAR-X as illuminators are derived and compared.
