Abstract

In this paper we analyze the reason why the QR-factorization is a very useful method for estimate the atmospheric delay in the unwrapped step of the SAR interferometric processing. We compute the solution of phase delay parameter model and confront the result with the GPS data metrics and the result from the Saastamoinen model. It is important to develop the new method for estimate the atmospheric phase delay and errors unwrapping procedure without the GPS or metrological data.
