A Wave Height Meter for Ocean Going Vessels Using a Simple Microwave Doppler Radar

Abstract

Asimple wave height meter is proposed using a simple microwave radar which has two detec ・ tors separated え ε ／ 8 (λ g ； microwave wavelength in waveguide) from each other inside the same wave ・ guide where a Gunn oscillator is placed ． Afield test is carried out at off − Tateyama by placing the doppler radar at the bow of the ship ，5meters above the see leve1 ， The result agrees reasonably with that obtained simultaneously
