A study of height measurement by using cross-track interferometric SAR - Comparison between airborne and spaceborne SAR

摘要

For height measurement of large area, the cross-track interferometric SAR (XTI SAR) technique becomes popular. The XTI SAR uses the relation between the phase difference of receiving signal of two antennas separated in cross-track direction and the target height. In this study, the height measurement algorithm using the phase difference is discussed in terms of the error.
