According to the increasing maritime trades and development of marine transportation, ship's navigation information must be provided not only to prevent an accident but also to ensure safe navigation. To get it, in general, radar and AIS are now in use, but do not integrate fully to each other. In this study, we introduce preliminary results of field experiment to merge both data in real-time. FMCW (Frequency Modulated Continuous Wave) radar and AIS system were used for monitoring ships in Pyeongtaek port, located on the west coast of Korea. The radar, developed by SIMRAD provides preprocessed data which can be handled by user through SDK program. First, an image generation procedure was performed from spoke data, and time series of the imagery was processed to detect and track ships. Consequently, we succeeded in simultaneously displaying ships from both FMCW radar and AIS. In the future, a matching work will be made to integrate the two data.
