Abstract. In this paper, we studied on Maximum Likelihood Height Estimate (MLHE) method to invert elevation using Multi-Baseline InSAR (MB-InSAR) Data. Then a set of simulated data were adopted to do the experiment to illustrate its availability. Meanwhile, this paper also presents the advantages and disadvantages of this approach with analysis of the influence of phase, baseline and range error on elevation inversion, as well as the following attention.
