Abstract
Radiometric measurements obtained from scanning sensors are useful for deriving one-dimensional spatial statistics of background. This paper introduces a local spatial statistic, the "differential length scale," that is particularly relevant for using the measurements to predict clutter leakage in proposed sensor systems. A method is given for calculating the differential length scale in the presence of measurement sensor noise, and the relationship of the differential length scale to the usual power spectrum length scale is described. Computer simulation experiments show that RMS clutter leakage from two-dimensional images can be predicted within 10% accuracy using only the differential length scale of one-dimensional slices of the image.
