A simple wave height meter is proposed using a simple microwave radar which has two detectors separated λ_g/8 (λ_g; microwave wavelength in waveguide) from each other inside the same waveguide where a Gunn oscillator is placed. A field test is carried out at off-Tateyama by placing the doppler radar at the bow of the ship, 5 meters above the see level. The result agrees reasonably with that obtained simultaneously by the conventional ultra-sonic wave height meter at the same position. Since the doppler radar and the signal processing circuit are quite simple in construction and inexpensive, it is expected after some more field tests that the present wave height meter will be widely used on merchant ships. A simple circuit to indicate the significant wave height is also proposed.
