Abstract

In this paper a method for baseline estimation is presented that is based on a Kalman filter and uses co-registration parameters of the interferometric SAR images. It comes along with the following advantages: No need for corner reflectors. No restriction to flat terrain in the scenes. Independence of orbit data. Moreover, it allows the determination of time varying baseline parameters and is independent of the accurate knowledge of the height of tie points
