Abstract
Method for numerical modeling of scattering characteristics of air targets with turboprop engines including secondary modulation spectra of signals reflected by stated objects is considered. Earlier developed by authors high-frequency asymptotic method [1, 2] based on estimation of contributions of the smooth and edged segments of object surface to scattered field is used for modeling. Results of calculations of helicopter radar cross section (RCS) and modulation spectra are demonstrated.
