Wave observation apparatus using navigational radar has been recently developed and set up at the Awaji Marine Experiment and Practice Centre of Maritime University of Kobe facing to the Harima-nada sea. This apparatus basically consists of a usual navigational radar, a data sampling and storing unit, and a personal computer. The highest frequency of the data sampling and the data storing memory are 120 MHz and 8 MB, respectively. The wave analyzing system has been also developed to obtain the two-dimensional informations of waves, the wave length and propagational direction of prevailing waves, from radar sea clutter. These observational and analyzing systems worked sufficiently good. Wave observations and analyses were made in 4 cases when the winds blew strongly from the west. Their results were consistent reasonably well with visual observations and estimations based on wave spectra. Studies on the simulation image of radar sea clutter from irregular waves have been also made.
