Paper Abstract

The permafrost and the seasonal frozen ground cover an extensive area in Qinhai-Tibetan Plateau. The surface displacement by seasonally freezing bulge and thawing subsidence are main hazards for engineering construction in permafrost regions. For detecting the subsidence at permanent frozen area, we try to study the interferometric method of monitoring the deformation at permafrost area using PS and SBAS technique with time-series EnviSat ASAR data. The characteristics of coherence at permanent frozen area about season change of difference object on the ground and inherent reason is important factor for the change detection and selection of stable scatters. This paper studies coherence characteristics of different ground objects at permanent frozen area., useing 13 scenes time-series ASAR data from Jan. 2004 to June 2006 at the Beiluhe test site in the Qinhai-Tibetan Plateau. The coherence characteristics showed big difference, which are the fundamental for permafrost subsidence detecting using SAR interferometry in the Qinhai- Tibetan Plateau.
