A prototype IDL computer code called AutoFusion10 has been written to test a method calledWave Data Fusion (WDF) which uses the ship as a wave buoy to correct wave heights measured with a WaMoS II wave radar processor and X-band navigational radar. The purpose of the system is to measure accurate seaway statistics and directional wave spectra from shipboard equipment and sensors for input to various operator guidance systems. The system displays the current significant wave height, peak wave period, peak wave direction and the 2D frequency-direction wave spectrum. This document describes the basic WDF theory, the system operation and software implementation. The code has matured to the point that it can be used as a working tool to provide accurate wave statistics and directional wave spectra from shipboard sensors. It has been tested and validated on a number of sea trials on the Canadian Navy research ship CFAV Quest and during a sea trial on a Kingston class coastal defence vessel. It has also been used to collect wave data on longer Quest deployments. The latest version of the code has been modified and tested in a recent Quest sea trial to work with measured ship motions that are not at the ship center of gravity (CG). This will be needed for use where it is not possible or it is inconvenient to have a motion sensor at the ship CG.
