        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.

          Integrated range-Doppler map and extended target classification with adaptive waveform for cognitive radar 

          Nieh, Jo-Yen (Monterey, California: Naval Postgraduate School, 2014-12);
          We set out to design an extended target classification scheme while determining the target’s range-and-Doppler location with the use of adaptive waveform for a closed-loop cognitive radar platform. To that end, this work ...

          Comparison of ambiguity function of eigenwaveform to wideband and pulsed radar waveforms: a comprehensive tutorial 

          Nieh, Jo-Yen; Romero, Ric A. (IET, 2017);
          The authors present a comprehensive research tutorial on the ambiguity function (AF) of eigenwaveform for extended targets compared to AFs of common radar waveforms (e.g. wideband and pulsed waveforms). They present new ...

          Noise adaptation and correlated maneuver gating of an extended Kalman filter 

          Spehn, Stephen L. (Monterey, California: Naval Postgraduate School, 1990-03);
          Extended Kalman filtering is used to provide estimates of the position and velocity of a target based upon observations of the target's bearing and range. Non-stationary noise is shown to degrade the performance of the ...
