A collaboration between NASA and the small business Aloft Sensing produced a new compact radar system that will enable researchers to leverage High Altitude Long Endurance (HALE) platforms to observe dynamic Earth systems. This new radar is small, provides highly sensitive measurements, and doesn’t require GPS for positioning; eventually, it could be used on vehicles [...]
