Target identification using bistatic highresolution range profiles

Abstract

A novel target identification scheme that utilises high-resolution range profiles (HRRPs), which are obtained using bistatic (BS) radar (BS-HRRPs) and four-dimensional (4D) parameter sets (PSs), is described. These PSs uniquely determine the BS-HRRPs. In the proposed scheme, a new feature to cope with the scale variances of the BS-HRRPs is devised by using the RELAX algorithm and the resampling process. In addition, a proper classifier to effectively exploit both the BS-HRRPs and 4D PSs is designed to improve the BS identification capability.
