Detection performance for statistical MIMO radar with identical and orthogonal waveforms

This paper studies the detection performance of two different statistical MIMO radar models: one transmits orthogonal waveforms, the other identical. As for the latter, assuming there is no violation of peak power constraints, the allocation of power among transmitters is unimportant from the viewpoint of detection. For full power transmission, the latter model may outperform the former at medium or low SNR, but is inferior at high SNR. Since they both share the same antenna configuration, properly shifting the transmission strategies may alleviate detection loss of a statistical MIMO radar.
