Abstract :
A ship mounted radar was developed to measure the wave heights from a moving ship. The radar antenna beam is pointed toward the unperturbed ocean surface from the forward superstructure of the ship. The distance changes due to the ocean waves and ship´s motions are tracked by a closed loop digital range tracker and the range measurements are recorded. Ship´s forward speed, roll, pitch, and heave are independently sensed so that their effect can be subtracted from the total radar range measurement to obtain the true wave heights.
