Based on the active absolute calibration of airborne radar
clutter characteristics of typical terrain (plain
hill
mountain and compound terrain) are measured at L-band HH polarization.Effects of the airplane postures on antenna pattern are modified.Analysis results of constant γ models
exponent model and four probability distributions are compared with data.It shows that γ model with index
n
and Weibull distribution
K distribution agree with the measured data and their statistical fitting parameters are also given.
