要約(英語): We have observed ground clutter from town and hill using an S-band radar with a frequency of 3.05GHz, a beamwidth of 1.8°, and a pulsewidth of 1.0μs, which is located on the campus of the National Defense Academy in Yokosuka-city. To investigate such ground clutter amplitude statistics, we introduce a compound distribution and the Akaike Information Criterion (AIC). We have found that the ground clutter amplitude obey the compound log-normal distribution with the shape parameters of σ1=0.424, σ2=0.232 for entire data and the compound log-normal, and compound log-Weibull distributions with the shape parameters of σ1=0.217 to 0.429, σ2=0.028 to 0.410 and c1=9.36 to 11.20, c2=17.00 to 23.81, respectively, for data within the beam width of an antenna. The number of the smallest AIC (MAIC) of the compound log-normal, and log-Weibull distributions are 8, and 4, respectively.
