Abstract：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.
