This article presents a novel circuit configuration which combines a high-voltage dc bias network with a distributed-amplifier iopology. This iype of circuii offers muliiociave bandwidih and improved eficiency in systems by reducing dc power consumption where the primary dc power is at voltage levels higher than required operaiing voltage for the active devices.Received 12-11 -90 ABSTRACT This article examines the polarimetric method of identijkation of a target in the presence of ground clutter. The clutter is modeled as a two-layer random medium. The complex scattering matrix for the clutter is obtained by using Born approximations carried to the second order to extract the crosspolarized scattered fields. The test target used is a loop of conducting wire oriented arbitrarily. It is found that the choice of polarization is one of the key factors if one has to identify targets in presence of clutter. This work does not take into account the mutual coupling between the target and the clutter sources. The important results are analyzed and discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
