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 real-time adaptive waveforms called maximum a posteriori probability weighted eigenwaveform (MAP-PWE) and match-filtered...
We propose an improvement to the maximum a posteriori probability weighted eigenwaveform (MAP-PWE) adaptive waveform design used in target recognition with a cognitive radar platform for which we call match-filtered PWE (MF-PWE). Our interest however is to include moving targets in the identification problem. Combining range-Doppler map (RDM) technique with the the PWE-based adaptive waveform techniques,...
In this paper we investigate the range resolution of transmit waveform designs matched to extended targets. We specifically look at eigenwaveform design which is also known as SNR-based illumination waveform design. To that end, we evaluate some ambiguity functions of radar systems employing eigenwaveforms. We consider some example targets and plot the corresponding ambiguity functions. Unlike traditional...
We propose a systematic process for designing a MIMO system with an arbitrary number of transmitting and receiving antennas, and evaluate (through simulation) the performance improvements that can be attained by employing our design. We present a general formula that can be readily used to determine the rate (i.e., the ratio of the number of symbols transmitted over the number of symbol intervals...
