Empirical models of the normalized radar cross section of monostatic freshwater clutter

Empirical models of the normalized radar cross section (NRCS) of linear co-polar monostatic freshwater clutter returns are presented. The models presented are similar to empirical models developed for sea clutter and relate the estimated NRCS to environmental conditions and scenario geometry. Model parameters are found through a least-squares fit. We compare our models to freshwater clutter data collected at S-band from an inland reservoir in eastern Massachusetts.
