A constant false alarm rate (CFAR) detector for RADARSAT-2 along-track interferometry
Canadian Journal of Remote Sensing, 2005 Canada's RADARSAT-2 synthetic aperture radar (SAR) satellite will be equipped with an experimental ground moving target indication (GMTI) mode, which makes use of the "dual-receive" capability of the RADARSAT-2 antenna to provide two apertures aligned in the along-track direction.
