The problem of performing automatic high resolution radar imaging of noncooperating maneuvering aircraft is investigated. In order to define the main features of the radar processor, a numerical model of the system which makes use of an electromagnetic model of the moving aircraft so that the actual, complete operating conditions can be simulated has been developed. The availability of such a numerical tool avoids the need to carry out long and onerous experimental tests. In this framework an automatic high-resolution radar imaging technique has been developed. The imaging algorithm provides parameters useful for target classificatio
The procedure proposed by F. A. Sikta et al (IEEE Trans. Ant. Prop. , vol. AP-31, pp. 584-585, July 1983) is easily and efficiently improved by conveniently utilizing the uniform geometrical theory (UTD) solution for double diffraction in the far zone of a plane wave. It is shown that the same equivalent-current concept can be applied to treat the case of plates with a dielectric coating, which are approximately represented by a surface-impedance boundary condition. To this end, the solution given by G. D. Maliuzhinets (1958), for the diffraction at the edge of a wedge with two different surface-impedance faces, is suitable to define first-order equivalent currents at the edges of each strip
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.
