Indirect method of RCS estimate of conducting target in random medium

Abstract

This paper discusses an indirect estimate of the RCS of a conducting cylinder with a partially convex cross-section under the condition that the backscattering enhancement occurs in a random medium. Once we evaluate the spatial coherence length (SCL) of incident waves around the cylinder in random medium, we may approximately estimate the RCS from the RCS in free space with beam wave incidence in which the spot size equals the SCL. This method is restricted only to the case where the SCL is larger than the target size.
