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