A New Method to Create a Virtual Third Antenna from a Two-Channel SAR-GMTI System

open access: yes, 2007
Two-channel SAR-GMTI systems are suboptimal for moving target motion parameter estimation. Indeed, the ATI phase estimate of the across-track velocity component for a moving target is biased to lower values depending on the target signal to clutter ...

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 ...

Improved Tropical Cyclone Wind Estimation Using Dual‐Polarization C‐Band SAR and Machine Learning

open access: yesEarth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Tropical cyclones (TCs) characterized by extreme wind speeds present severe hazards to human life and infrastructure. Spaceborne synthetic aperture radar (SAR) has emerged as a critical observational tool for TCs, owing to its all‐weather, high‐resolution imaging capabilities.
