ABSTRACT:
A wave measuring buoy for measuring ocean surface wave amplitude and frequency is disclosed. The buoy includes a single-axis accelerometer suspended as a pendulum inside a water-proof housing. The waterproof housing is connected to and beneath the flotation hull of the buoy and is located at the center of rotation of the buoy assembly so that the accelerometer is substantially insensitive to roll and pitch motions of the buoy. The output of the accelerometer is an analog signal proportional to the vertical (heave) acceleration of the buoy. A frequency transfer calibration can be applied to the accelerometer output to compensate for the mass, size and resonant heave behavior of the buoy.
