Shuttle Radar Topography Mission (SRTM) Calibration of the X-SAR-System and Validation of the X-SAR Products

Abstract

The heart of the SRTM is a SAR interferometer using the existing SIR-C/X-SAR hardware in the shuttle cargo bay augmented by secondary C- and X-band receive antennas mounted at the tip of a 60 m boom. The most critical part of X-SAR electronics are the boom cables, where we expect high temperature variations between -70 C and +50 C
