Radar target classification using DOA information

This is an application paper where existing ultra wideband (UWB) direction of arrival (DOA) techniques are utilized for estimating the direction of arrival of a radar signal with respect to the broadside of an antenna array. Such arrival information (or target azimuth) is then invested in improving the recognition performance of an unknown target. This application examines the impact of knowing the exact target azimuth position on the classifier´s performance. The paper uses real UWB radar data of commercial aircraft models recorded via a stepped frequency radar. The classifier uses the target high range resolution (HRR) profile that is dependent on the target´s aspect angle.
