DBF ocean radar can detect surface currents widely with high resolution in all weather conditions. We developed 24-hours real-time oceanographic monitoring system, which based on automatic figuring system for surface currents and wireless communication system with high-speed packet communications (up to 384 bps). Figures of surface currents can be delivered every 15 minutes with time lag of about 45 minutes through the Internet. The Dragon System is feasible for emergency observation after sudden ocean accident such as oil spills because of high portability. Field observations showed a measurable rating is more than 90% within 15 km along the receiving beam lines. Amount of measuring points in one operation periodically change over time. Its fluctuations were related with tidal variability.
