This book presents a novel non-intrusive infrastructure monitoring technique based on the detection and tracking of scattering centers in spaceborne SAR images. The methodology essentially consists of refocusing each available SAR image on an imposed 3D point cloud associated to the envisaged infrastructure element and identifying the reliable scatterers to be monitored by means of four dimensional (4D) tomography. The methodology described in this book provides a new perspective on infrastructure monitoring with spaceborne SAR images, is based on a standalone processing chain, and brings innovative technical aspects relative to conventional approaches. The book is intended primarily for professionals and researchers working in the area of critical infrastructure monitoring by radar remote sensing.

Exhaustively reviews the key recent research into non-intrusive infrastructure monitoring using a technique based on the detection and tracking of scattering centers in spaceborne SAR images Includes a chapter that is dedicated to the measurement campaign and presents a detailed comparison between the displacements that can be measured with different types of sensors Includes case studies that illustrate the high precision in situ displacement measurements using the methodology described in the book Includes supplementary material: sn.pub/extras
