Backscatter of a Large Rotating Conducting Cylinder with Arbitrary Cross Section.

Abstract

A quasi-stationary method in conjunction with GTD (geometrical theory of diffraction) techniques is used for calculating the backscattered field from a large rotating conducting cylinder with arbitrary cross section. Using this method, the scattered field at each time t is obtained as if the cylinder were stationary. The power density spectrum is then obtained using Fourier transformation. The backscatter power density spectrum of a large rotating cylinder consists of discrete spectral lines. For an orthogonal polygon-cylinder, the backscatter power density spectrum is symmetric about the incident frequency. A modal expansion solution is also obtained for verifying the results obtained by using GTD techniques. (Author)
