Abstract

The Environmental Research Institute of Michigan (ERIM) and Horizons, Inc. have completed the development, calibration and evaluation of the Advanced Research Projects Agency (ARPA)/US Army Topographic Engineering Center (TEC) funded IFSARE (Interferometric Synthetic Aperture Radar for Digital Terrain Elevations) system. This system rapidly produces geocoded SAR imagery and digital terrain elevation data. The dual-channel, X-band SAR is installed in the ERIM Learjet 36. The ground processor was developed in collaboration with the NASA Jet Propulsion Laboratory. The system produces 1.5 to 3.0 meters (1 sigma) absolute accuracy three-dimensional terrain elevation data over large areas without the use of ground control points. Several examples from recent data collections are presented
