Numerical Simulation of SAR Image for Sea Surface

Remote Sensing, 2022
Based on the simulated signal, a numerical simulation method of synthetic aperture radar (SAR) imaging for time-varying sea surfaces is proposed, which is helpful to study the SAR imaging mechanism of time-varying sea surfaces so as to better extract ...

Do data from the RISMA soil monitoring network support agricultural modeling requirements?

Vadose Zone Journal, Volume 25, Issue 4, July/August 2026.
Abstract The Real‐Time In‐Situ Soil Monitoring for Agriculture (RISMA) network provides soil water and agri‐environmental data for conceptualization, calibration, and validation of remote sensing and modeling products for Canadian agriculture at 32 stations in seven watersheds in Saskatchewan, Manitoba, and Ontario.

Integrating Ice Analyses and Varying Floe Size Parameterization Into Great Lakes Ice Prediction

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Accurate prediction of Great Lakes ice cover is critical for regional weather, navigation support, and safety. Current operational models often exhibit biases, such as over‐prediction of ice concentration and delayed spring melt, potentially due to simplified parameterizations.

Bias-Corrected RADARSAT-2 Soil Moisture Dynamics Reveal Discharge Hysteresis at An Agricultural Watershed

Remote Sensing, 2023
Satellites are designed to monitor geospatial data over large areas at a catchment scale. However, most of satellite validation works are conducted at local point scales with a lack of spatial representativeness.

The RADARSAT-2 SAR processor

Canadian Journal of Remote Sensing, 2004
The RADARSAT-2 synthetic aperture radar (SAR) processor processes RADARSAT-2 signal data into georeferenced and geocoded imagery. The processor is a subsystem of the RADARSAT-2 ground segment and is referred to as the processing and distribution subsystem (PDS).

Changes in Arctic Sea Ice Lead Width Distribution: Model Development and Experiments

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract Sea ice leads play a significant role in the atmosphere‐sea ice‐ocean systems. Model representation of leads of varying widths is desirable to enhance our understanding of the behavior of leads and associated processes. We have developed a lead width distribution (LWD) conservation equation to explicitly simulate the evolution of leads of ...

Assessment of the X- and C-Band Polarimetric SAR Data for Plastic-Mulched Farmland Classification

Remote Sensing, 2019
We present a classification of plastic-mulched farmland (PMF) and other land cover types using full polarimetric RADARSAT-2 data and dual polarimetric (HH, VV) TerraSAR-X data, acquired from a test site in Hebei, China, where the main land covers include

RADARSAT-2 ground segment

Canadian Journal of Remote Sensing, 2004
The RADARSAT-2 ground segment has been designed based on the need to support the advanced capabilities of the RADARSAT-2 spacecraft, the need to support a commercial mission with increased data and order volumes, and the body of experience and lessons learned from the operation of the RADARSAT-1 mission. The design was produced in consultation with the

Simultaneous Generation of Topographic Models and Manning Roughness Coefficient Maps From Tri‐Stereoscopic Satellite Images: Application to the Huarmey River, Peru

The Photogrammetric Record, Volume 41, Issue 195, July‐September 2026.
Tri‐stereoscopic PeruSat‐1 imagery enables the simultaneous generation of 0.70 m‐resolution topography and spatially distributed Manning roughness maps, achieving 0.434 m vertical accuracy. Integrated into HEC‐RAS, these products provide consistent, high‐resolution inputs that improve hydraulic modelling and flood risk assessment in data‐scarce river ...
