The JERS-1 (Japanese Earth Resources Satellite) Synthetic Aperture Radar (SAR) is a high-resolution, all-weather imaging radar. JERS-1 was launched by the Japan Aerospace Exploration Agency (JAXA), aboard a Japanese H-1 launcher.  Its Global Forest Mapping Program mapped important forests of the world: Southeast Asia, Africa, Central America, South America (Amazon Basin), and Boreal North America.
