摘要：

We observed sea clutter of sea area in the east of the Daini Kaiho sea fort in Tokyo Bay using an X-band Radar, and we obtained the data of 21,996 cells by observation of consecutive 47 times. In order to investigate the statistical properties, we made estimation of parameters by maximum likelihood estimation and a test of goodness of fit by AIC as models for Weibull, log-Weibull, and log-Normal distributions. As a result, the reflected intensity distribution of sea clutter obeyed Weibull distribution better than any other distributions, and so we made a study using shape parameter of Weibull distribution, it was found that sea condition such as swell and wind wave affect the statistical properties of sea clutter. © 2015 The Institute of Electrical Engineers of Japan.
