Abstract
Ground clutter of cultivated land was measured using an L-band long-range air-route surveillance radar (ARSR) having a 3.0 μs pulsewidth and a 1.23° beamwidth at very low grazing angles between 0.21° and 0.32°. 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
