Land backscattering model for millimeter wave radar

The main computation relations for determination of MMW radar land clutter statistical characteristics are analyzed. Expressions for normalized RCS determination of different surface types and polarization features of backscattering signals are discussed. Spatial and temporal statistical characteristics of the quadrature components and the amplitudes of scattered signals are analyzed. It is shown that the amplitude pdf is approximated by the Weibull´s law and the distribution of quadrature components is described by the compound Gaussian law. The spatial distributions for different terrain types are presented. As a result, the algorithms for radar clutter modeling at millimeter band of radiowaves are obtained taking into consideration the spatial statistics of natural land surface.
