Abstract

Elevation measurement using Synthetic Aperture Radar (SAR) is one of fundamental techniques in remote sensing. Interferometric SAR (InSAR), which is the most popular technique of elevation measurement using SAR, uses the phase differences between the signals received by SAR antennas. InSAR requires Ground Control Points (GCPs) to measure absolute elevation values, although GCPs cannot be obtained in emergency situations. In addition, rapid observation, i.e., on-board processing, is expected in emergency situations. Addressing the above problem, this paper proposes an elevation measurement method using interferometry and radargrametry from single-pass airborne SAR images. Through the experiments, we demonstrate that the proposed method exhibits efficient performance in elevation measurement.
