Numerical Computation of the Radar Cross Section of Rockets and Artillery Rounds

Abstract

This report investigates the modeling of radar scattering from rocket, artillery, and mortar (RAM) targets in 4 radar frequency bands: L, S, C, and X. Three targets are selected for this study: a 155-mm artillery round, and a 107-mm rocket, with and without stabilization fins. The radar cross section (RCS) calculations are performed by 2 different methods, implemented by the FEKO and AFDTD electromagnetic simulation software packages, over all the possible aspect angles. The solutions obtained by the 2 methods are compared for accuracy validation. The RCS analysis includes prediction of the variation with frequency and the azimuth angle (for non-symmetric targets), as well as a comparison among the 4 frequency bands of interest. The target signature calculations in this study are an important tool for radar engineers in system performance evaluation.
