This volume is devoted to the Persistent Scatterer Technique the latest development in radar interferometric data processing. It is the only book on /Permanent Scatterer (PS) technique of radar interferometry and it details a newly developed stochastic model and estimator algorithm to cope with possible problems for the application of the PS technique. The STUN (spatiotemporal unwrapping network) algorithm developed to cope with these issues in a robust way is presented and applied to two testThe Permanent Scatterer Technique.

Conclusions andThis volume is devoted to the Persistent Scatterer Technique the latest development in radar interferometric data processing. Using this technique millimetric displacements can be observed at hundreds of thousands of targets that are affected only slightly from temporal and geometric decorrelation such as the walls and the roofs of houses lamp posts grates window ledges etc. All acquired data can be used by this technique which enables the analysis of displacements since 1992 in any area worldwide using the archived historical data of the ERS1 and ERS2 satellites. Data of other current and future sensors can also be processed using this technique. The original PS algorithm is revisited based on the main literature and possible weak points are identified. The STUN (spatiotemporal unwrapping network) algorithm developed to cope with these issues in a robust way is presented and applied to two test sites. For the Berlin area two data stacks of adjacent tracks are analyzed to assess the quality description provided by the STUN algorithm. For the Las Vegas test site a combination of ERS and ENVISAT data is performed to estimate significant linear and seasonal displacements. brAudiencebrThis book is of interest to scientists and professionals in geodesy and geophysics working with Radar Interferometry studying urban displacements earthquakes or volcanoes.Only book on Permanent Scatterer technique of radar interferometry/Explains the Permanent Scatterer technique in detail possible pitfalls and details a newly developed stochastic model and estimator algorithm to cope with possible problems for the application of the PS technique/The use of Permanent Scatterer allows very precise measurements of the displacement of hundreds of points per square kilometer/Describes the only technique currently able to perform displacement measurements in the past utilizing the ERS satellite data archive using data acquired from 1992present/Shows how to interpret results obtained by radar interfer
