Interferometric synthetic aperture radar (InSAR): A long-term monitoring tool
2015Interferometric synthetic aperture radar (InSAR) imaging is a growing remote-sensing technique. The term “interferometry” draws its meaning from two root words: interfere and measure.

In this study, we developed a new SAR/InSAR-based land-cover classification algorithm for estimating surface roughness, a key parameter that is critical for accurate compound flood modeling. We successfully classified the Greater Houston area and New Orleans into nine classes with distinct surface roughness using L-band ALOS PALSAR-1 data.

Anomaly Detection in Bridges Using Interferometric Synthetic Aperture Radar (InSAR)
Proceedings of the 15th International Workshop on Structural Health MonitoringStructural 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.

Since the early 1990s, sinkholes and wide, shallow subsidence features (WSSFs) have become major problems along the Dead Sea shores in Israel and Jordan. Sinkholes are readily observed in the field, but their locations and timing are unpredictable. WSSFs are often difficult to observe in the field.

Tianjin is one of the cities in the north of China where the land subsidence has most seriously developed. The land subsidence has been lasting for 50 years. In the paper, we use permanent scatterers interferometric synthetic aperture radar (PS-InSAR) technique to detect and measure ground movement in this area.

Interferometric synthetic aperture radar (InSAR) is capable of measuring ground-surface deformation with centimeter-to-subcentimeter precision at a spatial resolution of tens of meters over a large region. With its global coverage and all-weather imaging capability, InSAR has become an increasingly important measurement technique for constraining magma

The availability of a near-global digital elevation model derived from the Shuttle Radar Topography Mission (SRTM) provides archeologists a new tool to complement other remote sensing data. SRTM data not only provide basemaps for geographic information systems and aid in geometric corrections, they also provide data for visualizations and animations ...
