High frequency inverse scattering and the Luneberg-Kline asymptoticexpansion

The problem of estimating the relative distance to individual scatterers within a complicated multiscatter target from radar backscattered signals is addressed. The scattered signal amplitudes produced by these scatterers are estimated. Such information can be useful for detection and identification of targets. An extension is described of the linear prediction algorithm for estimating these quantities applied to a signal model given by the Luneberg-Kline asymptotic expansion for electromagnetic scattering. This model includes the geometrical optics signal model as a special case
