Radar Image Simulation: Validation of the Point Scattering Method. Addendum

The purpose of this report is to present the additional results of applying the Point Scattering Model for radar image simulation to three (3) new cases. This work is supplemental to that previously reported. The work was sponsored by the U. S. Army Engineer Topographic Laboratories (ETL). The results reported were obtained for four (4) simulations corresponding to four specific altitudes in the terminal trajectory of a guided missile (three of the simulations are new), each successively lower. The sequence of four simulations was tested against actual radar data of the same site via the Correlatron. The correlation tests showed performance of simulations produced by the PSM to be acceptable in three cases, and to be unacceptable in one case. The unacceptable performance was explained by geometric errors inadvertently introduced into the data base and was not produced by the simulation method. Addendum to Rept. nos.
