Interferometric Ka-band SAR with DBF capability

An interferometric SAR (InSAR) Ka-band instrument is presently being studied under ESA contract. At Ka-band, a single-pass single-platform interferometric SAR instrument with Digital Elevation Map performance at HRTI-3 standard level seems feasible. An architecture developed under this contract is described. It depends heavily on the digital beam forming techniques SCORE and MAPS. Design considerations and InSAR performances are reported.
