3.6. HIGHER MOMENTS AND PERCENTILES IN MEASURED LAND CLUTTER SPATIAL AMPLITUDE DISTRIBUTIONS
The subject matter of Chapter 3 is multifrequency low-angle land clutter amplitude distributions as measured from large, repeat sector, spatial macroregions of visible terrain. Previously, the mean levels (i.e., first moments) in these distributions have been under discussion. Here, in Section 3.6, the repeat sector clutter distributions are brought under more complete description by numerically specifying their higher moments, namely, the ratio of standard deviation-to-mean (which is a normalized measure of the second moment), the coefficient of skewness (or normalized third moment), and the coefficient of kurtosis (or normalized fourth moment), and ...
