In this paper we describe a new method for aligning High Resolution Radar (HRR) range profiles for classification purposes. We describe the effects of Translational Range Migration on the phase of the Fourier transformed profiles, and show how the problem of finding an absolute alignment of HRR profiles can be described as a problem in phase estimation.(More)
For a decade, NATO nations, both on their own and within NATO groups have performed studies in the field of Twodimensional Inverse Synthetic Aperture Radar (2D-ISAR) and High Resolution Radar (HRR) Range Profiles. During that work high-quality radar imagery data of aircraft has become available through measurement campaigns. It was shown that the(More)
Antenna arrays suitable for passive covert radar applications are discussed in this paper. The system design requirements are accurately presented and reflected in the array parameters. Direction finding techniques are evaluated in connection with a circular array antenna configuration. Initial theoretic results obtained with a passive covert radar(More)
