New horizons for over-the-horizon radar?

Abstract
Science stands to benefit from the quarter century of research and development, and $1.5 billion spent by the Air Force, to deploy six over-the-horizon (OTH-B) air-defense radars, now targeted for shutdown. Opportunities for environmental research and services on a grand scale beckon to anyone who can afford to operate and maintain them. Tests show the radars' potential for high-resolution mapping of ocean-surface wind, waves, and currents.
