Cubic Splines in Clutter Modeling.

Abstract

In developing clutter models, Raytheon used smoothing cubic splines to obtain analytical expression for the clutter amplitude distribution functions. This application is believed to be unique. This report has been prepared to describe in detail the development of the smoothing cubic spline. An explanation of the large oscillations in the error obtained in the fit or data match for large clutter values is given, and a method that would avoid the oscillations is discussed.
