Abstract : In a study by Papa and Woodworth, the mean and variance of the diffuse power scattered from a clutter cell were examined as a function of cell size for one-dimensionally rough surfaces. Their study was performed for horizontally polarized incident and scattered fields. In this report their work is expanded to include vertical and arbitrary linear polarization. Scattering statistics and polarization effects will be examined using a theoretical model based upon physical optics. The present study shows that as the size of the clutter cell is decreased the statistical distribution of the scattered power deviates from Rayleigh. Also. It Is shown that the tilt angle of the incident linear polarization has little effect on the statistics of the scattered wave.
