摘要

This paper presents a detailed study of geocoding algorithms for interferometric SAR data from airborne sensors. They allow to relate a phase value in slant-range coordinates to a position in a cartesian reference system and, hence, a height value on a topographic map. Two basic approaches, which follow forward or backward strategies, are proposed in this paper. Another aspect is related to the kind of the acquisition mode: single- or repeat-pass. In general, a wide variety of techniques and combinations (single or repeat pass, direct or indirect transformations, one or two steps, zero-Doppler or squinted geometry) exist. This paper reviews the state-of-the-art of these combinations, as well as their evaluation, comparison and discussion by means of real data from the DLR's E-SAR system. The discussion includes the problem of polarimetric data geocoding. In that case, the map-projected height information derived from a X-band single-pass system is used to geocode non-interferometric channels (for example polarimetric L-band data).
