Abstract:The validation of a radar system for making topographic measurements is described. The system is an interferometric SAR radar flown by Norden Systems in late 1992 and early 1993 under an ARPA-sponsored program. Both absolute and relative height measurements were made, with aircraft position referenced to an INS/GPS and a separate differential GPS. An initial accuracy prediction was obtained from a complete system error analysis.Confirmation of this prediction was a non-trivial task, which consisted of making c… Show more
