Abstract

An absolute-phase algorithm is used in an interferometric radar mapper to determine the unknown constant number of cycles of phase difference after phase unwrapping and, thus, the absolute topography. Using a model and a simulation, the author computes the accuracy of one such algorithm and compares it to the results for an actual system. The algorithm´s accuracy for other systems is predicted
