A unique combination of antennas could revolutionize remote sensing

Bigger antennas are better, at least according to researchers interested in geospatial monitoring. That's because higher resolution in monitoring applications requires larger apertures. So imagine the excitement in the remote sensing community when a researcher from Leidos, a government consulting firm, developed an idea that dramatically increased the effective aperture size of a remote radio-frequency monitoring system simply by tying a rotating antenna to a flat "sparse" array.
