ABSTRACT: Baseline is an important
parameter of radar interferometry. Generally, it can be estimated by satellite
orbital data or ground control points. In this paper, an adaptive method is
proposed to estimate it with combination satellite orbital data, and the
accuracy of baseline estimated can be improved without ground control points;
actual data of ERS and ENVISAT ASAR have been used in algorithm development and
the final obtained elevation shows that the precise orbit data is more accurate
than original orbit data in estimating baseline.
