ASAR ERS Interferometric Phase Continuity

Kurzfassung

During the last ten years, a long history of data was acquired by the SAR sensors on the satellites ERS-1 and ERS-2 offering a wide range of interferometric applications. In 2002, the more advanced satellite ENVISAT was launched. The SAR on board of ENVISAT (ASAR) can continue the success of the remote sensing mission of the ERS satellites and preserve or even increase the value of the archived ERS data. The subject of this study is to demonstrate the continuity of the interferometric measurements by the combination of the SAR scenes of the different sensors to interferograms (cross interferometry).
