Abstract
An exact and closed-form algorithm for InSAR geolocation is studied, then on the basis, an analysis of error propagation between measurements and geolocation solution was given. At the same time, from a new point of view, we propose a new method focused on the compensation of the difference of the slant ranges of two satellites. Eventually, appalling a method of baseline estimation which based on GCPs, we can obtain high precision baseline estimation from geolocation solutions after error compensation.
