Monitoring surface changes in discontinuous permafrost terrain using small baseline SAR interferometry, object-based classification, and geological features: a case study from Mayo, Yukon Territory, Canada

open access: yesGIScience & Remote Sensing, 2019
Permafrost-induced deformation of ground features is threating infrastructure in northern communities. An understanding of permafrost distribution is therefore critical for sustainable adaptation planning and infrastructure maintenance.

Evaluation of Radarsat-2 quad-pol SAR time-series images for monitoring groundwater irrigation

open access: yesInternational Journal of Digital Earth, 2019
Groundwater assists farmers to irrigate crops for fulfilling the crop-water requirement. Indian agriculture system is characterized by three cropping seasons known as Kharif (monsoon), Rabi (post-monsoon) and summer (pre-monsoon).

RADARSAT-2 SAR antenna

open access: yesCanadian Journal of Remote Sensing, 2004
The synthetic aperture radar (SAR) payload is made up of two major components, the sensor electronics (SE) subsystem and the SAR antenna. This technical note focuses on the RADARSAT-2 SAR antenna radio frequency (RF) and mechanical design and presents an overview of the antenna RF performance requirements and design trade-offs that led to the baseline ...
