Scattering characteristic from a cylindrical Salisbury screen with 1rad

This paper presents radar cross section results from a MLFMM model of scattering from a cylindrical Salisbury screen with 1 rad. Different from some previous researches, this study is concentrated on the results at high radar frequencies such as in I and J bands (9-11 GHz). Both normal and off-normal incidence is considered. According to our calculated results by MLFMM, it exhibits better scattering performance than the same size plate. In addition, we find that in the angle range of 70-90°, a few data of the latter are smaller slightly than those of the former. However, we believe it may not affect the application in fact. Finally, in order to study the interaction between incident wave and the cylindrical Salisbury screen, the distribution of surface current and charges at 9.8 GHz are presented.
