Researchers at the National Cheng Kung University and the National Applied Research Laboratories have integrated a mobile radar monitoring device onto a recreational vehicle (RV) and later to a ship. The functional core of the mobile X-band radar system includes an analog-to-digital system with a 20-megahertz sampling rate and 12-bit resolution. The spatial resolution of the radar image is 7.5 meters per pixel under this sampling rate. The sea-state monitoring system was most recently modified to operate on a container vessel with a 6,600 20-foot- equivalent-unit capacity. Mounting the system on a moving vessel requires a global positioning system and compass to correct the radar image signals. Operators using the marine X-band radar and a computer with high-speed data acquisition can extract continuous sea-surface image sequences. Operating the radar on an RV requires a generator, an elevated boom and a stabilization system.
