In this paper, we propose an integrated scheme to identify an extended moving target while trying to correctly locate its peak range-Doppler cell. The scheme is extended to handle multiple target responses. The cognitive radar platform uses adaptive waveform based on the eigenwaveform. Two realtime adaptive waveforms called maximum a posteriori probability weighted eigenwaveform (MAP-PWE) and match-filtered PWE (MF-PWE) are combined with range-Doppler map (RDM) technique to execute target type identification for moving extended targets. Joint RDM cell localization and target identification performance comparison between a traditional pulsed wideband waveform, MAP-PWE, and MF-PWE techniques are shown. It is noted the MF-PWE performs better than the wideband and MAP-PWE.
