Development of Mini-Buoy for short term measurement of ocean wave

The authors have developed a small wave buoy as “Ultra-Small-Directional-Wave-Buoy” from 1997. In recent years, The demand of short term wave measurement such as verification of wave radar system and speed trials of new ships is increasing, but general wave buoys are large, expensive and for long term measurement. For such usages, smaller and lighter “Mini-Buoy” is developed.
