Abstract :
The Office of Naval Research (ONR) sponsored the design and fabrication of a wave follower system. The wave follower is a mechanical device designed to position sensors above and below the sea surface. Instruments are mounted on a platform suspended on an endless loop of cable rigged between two pulleys; an idler pulley below the sea surface and a drives pulley above the surface. Data obtained with the wave follower system confirms sea surface data obtained with synthetic aperture radar or other remote sensors. ONR´s wave follower was originally designed and built by the Jet Propulsion Laboratory. Messrs Harris and DeCicco of EG&G Washington Analytical Services Center Inc. Performed all design and engineering to modify ONR´s wave follower. This included replacing the direct current electric servo drive with one based on electronically controlled hydraulics and other modifications to increase the instrument payload and frequency response
