The on-board experiment of the marine radar wave observation system has been carried out on waters in and near Osaka Bay and near around Izu-Oshima Island and Gotou Islands for 30 days in total in 1994. For this experiment, two types of ships, a usual small pleasure boat and the experimental vessel at sea of Techno-Super-Liner, were used. This system can obtain 2-dimesional wave information, the wavelength and the propagational direction of prevailing waves, from radar sea echo signals. The wave measuring and analytical ability and accuracy of this system showed reasonably good. When winds were relatively weak, no information of the prevailing waves was obtained visually. But the system could analyze the propagational direction of swell eventhough its wavelength was not analyzed in some cases. When winds blew relatively strong and wind waves and swell were mixed, both were not distinguished visually. But the system could distinguish and analyze both of them separately with relatively good accuracy.
