Interferometric Synthetic Aperture Radar (InSAR) in the Context of Bridge Monitoring

, 2020
The structural health of critical transport infrastructure, such as bridges, is difficult to assess and monitor. Existing methods of evaluation rely predominantly on visual inspection and/or the installation of sensors to measure the in-situ performance of structures.

Anomaly Detection in Bridges Using Interferometric Synthetic Aperture Radar (InSAR)

Proceedings of the 15th International Workshop on Structural Health Monitoring
Structural Health Monitoring (SHM) plays a crucial role in supporting decision-makers by providing vital information on the structural integrity of bridges. Traditional SHM systems typically rely on in-situ sensors, which can be time-consuming to install and vulnerable to failure during extreme weather events.

Assimilation of L-band interferometric synthetic aperture radar (InSAR) snow depth retrievals for improved snowpack quantification [PDF]

The Cryosphere
Abstract. The integration of snow hydrology models and remote sensing observations via data assimilation is a promising method to capture the dynamics of seasonal snowpacks at a high spatial resolution and to reduce uncertainty with respect to snow water resources.

DATA OPTIMALIZATION IN PERMANENT SCATTERER INTERFEROMETRIC SYNTHETIC APERTURE RADAR (PS-INSAR) TECHNIQUE FOR LAND SUBSIDENCE ESTIMATION

, 2018
Since the introduction of the persistent scatterer technique (PS-InSAR) in the early 1999, the applicability of radar interferometry has increased considerably.In this research, PS-InSAR technique is proposed to retrieve the volume change of long-term continuously land deformation. This technique is used to analyze subsidence in Bandung City, West Java-
