Abstract : This report is a continuation of the previous study on simulation parameters. Additional cases studied in this report indicate that the minimum number of points per wavelength or per correlation length whichever is the smaller is around 5, the minimum number of surface samples is 25 and the minimum width of the illuminated area is 7 lambda or 7L whichever is the larger. These studies are still incomplete in that we have not considered enough variations in the surface rms height, surface rms slope and the ratio of the incident wavelength to the surface correlation. Keywords: Antenna radiation patterns, Fast fourier transforms. (jhd)
