摘要：
We observed sea clutter using an X-band Radar in some area of Tokyo Bay including ships on the Uraga Suido traffic route and the Daini Kaiho sea fort, and furthermore observed the sea condition. By analyzing the observed data statistically, we studied the effect of the sea condition for the statistical properties of the sea clutter. As a result, we showed that the sea clutter in case of including no target obeyed the Weibull distribution but that in case of including target tended to obey the Log-Weibull distribution or Log-normal distribution. And also we showed that correlation between the shape parameters c of Weibull distribution, Log-Weibull distribution and the significant wave height were strong. In addition, we showed that there was no correlation not only between the wave period and the shape parameter c of Weibull distribution, but also between the wave period and the shape parameter c of Log-Weibull distribution. © 2011 The Institute of Electrical Engineers of Japan.
