GMTI for Squint Looking XTI-SAR with Rotatable Forward-Looking Array

Sensors, 2016
To realize ground moving target indication (GMTI) for a forward-looking array, we propose a novel synthetic aperture radar (SAR) system, called rotatable cross-track interferometry SAR (Ro-XTI-SAR), for squint-looking application in this paper.
