TIME BEHAVIOR OF MULTIPLE SCATTERING

Abstract

Cross-polarized electromagnetic backscatter from a cylinder of underdense plasma is considered when the input is a r-f pulse of finite duration. The second Born approximation is employed. The dimensions of the scatterer are assumed large compared with the r-f wavelength and the correlation distance. For times sufficiently long after the pulse has ended, the 'cross section' is shown to fall off as the reciprocal of the time squared. An estimate is made of the effect of a non-uniform electron density and it is found that, provided the rate of decay is not too great, the cross-polarized backscatter and the directly -polarized backscatter arise from the same volume of the scatterer.
