Spectral Wave Data Analysis 

Spectral analysis identifies the distribution of wave energy in terms of frequency and direction, for which the AIM wave buoy sensor has a number of options. Non This Heave/Roll/Pitch combination as for directional measurement is traditional and typically employed for buoys with ‘discuss’ hull forms, but which is not necessarily appropriate for other hull forms, and in particular for larger buoys where pitch and roll response is inhibited by hull form and/or mooring arrangements. To increase the range of options therefore, the AIM sensor also allows for calculation of the directional spectrum from other combinations, such as heave with surge and sway measurements (this as typically employed by GPS buoys). Basically a number of combinations are supported between the buoy vertical and lateral motions.
