We observed sea clutter using a millimeter wave radar having a frequency 34.86GHz, a beamwidth 0.25°, and a pulsewidth 30ns. To determine the sea clutter amplitude, we introduce the Minimum Description Length (MDL) principle, which is more rigorous fit of the distribution to the data than the Akaike Information Criterion (AIC). It is discovered that the sea clutter amplitudes obey the log-Weibull distribution with the shape parameter of 19.19 for entire data and the Weibull and log-Weibull distributions with the shape parameters of 4.81 to 5.17 and 17.72 to 20.99, respectively, for data within the beam width of an antenna.
