Ground clutter of cultivated land was measured using an L-band long-range air-route surveillance radar (ARSR) having a 3.0 /spl mu/s pulsewidth and a 1.23/spl deg/ beamwidth at very low grazing angles between 0.21/spl deg/ and 0.32/spl deg/. To determine the ground clutter amplitude, we introduce the Akaike Information Criterion (AIC), which is more rigorous fit of the distribution to the data than the least squares method. It is shown that the best fits of ground clutter amplitude are the Weibull, log-Weibull, and K-distributions.
