In a method for interferometric radar measurement, at least two synthetic aperture radar (SAR) systems on satellite and/or missile-supported platforms illuminate a common surface area by means of microwave signals. A first SAR system sends a first radar signal on a first transmit frequency, and at least a second SAR system sends at least a second radar signal on at least a second transmit frequency. At least one of the at least two SAR systems receives the at least two interfering radar signals reflected on the common surface area, determines difference phases of the received radar signals from the interferograms, determines therefrom a drift of a system clock of the at least two SAR systems, and compensates the determined drift.
