Topography of sand covered bedrock using two-frequency airborne interferometric SAR measurements

This paper presents the application of Interferometric Synthetic Aperture Radar (InSAR) to estimate the height of the sand layer on top of the bedrock in deserts. This is anticipated to greatly increase the efficiency of oil field search and can have several applications for environmental and archaeological studies. The extension of InSAR processing to estimate the covered bedrock height through an iterative algorithm is introduced. The sensitivity of the proposed algorithm to system errors is investigated and its application to a common type of sand dunes is also presented.
