The Effect of Limiting upon the Mean Cross Section of Log-Normal Radar Clutter

A log-normal variate is described by its median value and by the standard deviation of In(¿c/¿m), where ¿c is the variate and ¿m is its median value. For radar applications, the mean value of the variate is useful, and this correspondence derives the effect upon the mean value of various degrees of limiting. Numerical results are presented in the form of a family of curves where the limit level is the abscissa and the resulting mean value is the ordinate.
