The purpose of this paper is to present Wave Finder Radar Scan Converter(WF-RSC) System that finds directional wave spectra using nautical radar. Applying this system to the real ocean, we can estimate the direction of waves using radar signals. It is useful to get information on the direction of waves during the sailing. The data obtained from the system makes it possible to automate the sailing vessels. For example, a vessel can be capsized if it sails in the opposite direction of waves. But it is not only safe but also useful for saving fuel that a vessel sails along the appropriate direction of waves. Moreover, we can get the information on the annual voyage through the constant analysis of waves' monitoring data. It makes possible to expect the life span of a ship and the point of repair time. This system includes high speed ADC(Analog to Digital Converter), SRAM, and PCI-bus interface to transmit lots of radar data rapidly. The field test was implemented at Haeun-dae Beach in Busan and at Wajin Beach in Pohang. And we could find the numerical value of wave direction using a time series of two-dimensional images through the 3D-FFT. It was confirmed that the expected direction of waves is corresponded with the actual direction of waves through the analysis of radar images.
