Abstract

Abstract

The scattering characteristics of an airplane model and the radar absorbing material covered on the model are simulated by the finite-difference time-domain (FDTD) method, and the time-domain echoes and frequency-domain radar cross section echoes of the model from nose-angle, side-angle and back-angle stimulated by an ns pulse are obtained. The results of the simulation and outdoor experiment show that the echo amplitude of the nose-angle is the lowest and that of the side-angle is the highest. The pulse-width of the nose-angle echo is the widest and that of the side-angle is the narrowest. The shape-stealth and material-stealth are not effective for ns or sub-ns pulse signals.
