Abstract : The principles underlying the use of radar to record sea-wave elements are described briefly and two methods of observing waves with a ship's radar are described. The first method is characterized by the fact that radar signals of the waves are studied in a circular radar screen, are photographed and decoded. The second method consists in the examination of signals on a linear radar scanner. The effect of ship rocking on the reception of radar signals involving variation in the spatial orientation of the radar beams and increased pulse intensity from the waves, errors in determining range and bearing of the target, etc. are discussed.
