Radar target recognition using least squares estimate

Abstract

A new scheme for radar target discrimination which is independent of an aspect angle is proposed in the frequency domain. A system of linear equations is constructed using the frequency response of air unknown target and stored natural frequencies of a particular target. Whether an unknown target is a particular target or not is determined using the defined least squares estimate or the normalized estimation error. The validity of the method is shown rising the method-of-moments (MM) frequency response. (C) 2001 John Wiley & Sons. Inc. Microwave Opt Technol Lett 30: 427-434, 2001.
