Paper Abstract

Range profiles generated by a high range resolution radar have been used for non-cooperative target identification, especially in cases when radar range-Doppler image cannot be generated due to various reasons. Since a range profile is inherently a transient phenomenon, underlying features may not be identified in the time domain or frequency domain alone.However, the joint time-frequency analysis may provide a localized time-frequency information for identifying significant features of targets. A basis set, which is natural to the signal and called the natural frame, can be derived from the signal's energy distribution in the joint time-frequency domain. In this paper, the natural frame decomposition is used for best representing radar range profiles, a time-frequency ridge detector is applied for finding the natural frame set, which can be used as the target features for classification.
