1st Edition
Ground Based Synthetic Aperture Radar
Ground Based Synthetic Aperture Radar (GB-SAR) is used to effectively mitigate natural disasters and monitor social infrastructures such as bridges, dams, and airport pavement surfaces. This book explains the fundamentals of radar technology, the principles of Synthetic Aperture Radar (SAR) image generation, and Interferometric SAR (InSAR) processing for observing small ground surface deformation less than 1 mm. More advanced MIMO radar for ground surface observation is introduced. The authors also provide examples of GB-SAR used for landslide monitoring and vegetation, to show its potential and limitations. Understanding this advanced technology and its applications will help readers plan and install the GB-SAR systems in real-life projects.
Features
- Introduces GB-SAR, an advanced tool that measures in-millimeter ground surface displacement.
- Explains how the GB-SAR system can be installed for landslide monitoring.
- Provides a new radar technology that monitors vibrations of infrastructures remotely.
- Discusses the advanced radar technology related to polarimetry and interferometry.
- Includes several case studies applying the tools and techniques discussed to natural disasters, such as landslides, volcanoes, glaciers, etc.
This book is intended for professionals in civil who deal with disaster mitigation and infrastructure monitoring, and those in electrical engineering, including radar technology. It is also an excellent resource for upper-level undergraduate and graduate students taking courses in remote sensing and photogrammetry, geography, geodesy, information science, engineering, and geology, as well as researchers and scientists interested in learning the techniques and technologies for collecting, analyzing, managing, and visualizing geospatial datasets.
1. Introduction. 2. Fundamentals of GB-SAR. 3. Installation and operation of GB-SAR. 4. Atmospheric Phase Delay. 5. Applications. 6. MIMO radar system.
