THE DEVELOPMENT OF A WAVE HEIGHT MEASUREMENT SYSTEM TO PROVIDE AUTOMATIC RECORDING OF SEA-STATE OFF-SHORE AT THE CARDIGAN BAY RANGE.
Abstract
A requirement has arisen at R.A.E. Aberporth to measure sea-state at considerable distances off-shore. To meet this requirement, it is necessary to define the surface profile of the sea at a given point to an accuracy of + or - 6 inches under maximum peak/peak wave conditions of 8 feet. A system has been developed based on a stable platform in the form of a spar-buoy insensitive to wave-motion; upon this is mounted a resistive type of electronic sensing unit to generate an electrical analogue of wave height, which is transmitted to a shore base by means of a telemetry link. This report describes the design features of stabilised spar buoys and the development of the electronic sensing unit ect.; it gives experimental data from tests and outlines the development of an engineered system for operational use.
