Radar target recognition using range profiles

With the increased availability of coherent wideband radars, there has been a renewed interest in radar target recognition. A large bandwidth gives high resolution in range which means target recognition may be possible. We examine some of the problems of classifying high resolution range profiles (HRRP), and investigate simple preprocessing techniques which may aid subsequent target classification. We apply these techniques to HRRP data acquired at a local airport using the Microwave Radar Division (MRD) mobile radar facility. We find that we can reliably distinguish between Boeing 727 and Boeing 737 aircraft over a range of aspect angles
