The statistical distribution of backscattering S from some randomly oriented simple configurations is considered in terms of the log-normal distribution. The log-normal parameters (mean and variance of ln S ), for arrays, cylinders, and plates are obtained and shown to afford an accurate description of their backscattering statistics over a wide range, for sizes in excess of a few wavelengths. A reason for this correspondence is obtained by noting that the backscattering pattern of an array may be expressed as a product of factors which are uncorrelated with respect to random sampling. A product of independent factors leads to the log-normal distribution. Finally, results for some randomly sampled simple antenna patterns are given.
