Design of Optimal Waveforms in MIMO Radar Systems Based on the Generalized Approach to Signal Processing
The authors consider the problem of waveform design for Multiple-Input Multiple-Output (MIMO) radar systems employing the generalized detector that is constructed based on the generalized approach to signal processing in noise. They investigate the case of an extended target and without limiting ourselves to orthogonal waveforms. Instead, they develop a procedure to design the optimal waveform that maximizes the Signal-to-Interference plus-Noise Ratio (SINR) at the generalized detector output. The optimal waveform requires a knowledge of both target and clutter statistics. They also develop several suboptimal waveforms requiring knowledge of target statistics only, clutter statistics only, or both.
