Abstract
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.
