摘      要：In this paper,a new correlated covariance matrix for Multi-Input Multi-Output(MIMO)radar is proposed,which has lower Side Lobe Levels(SLLs)compared to the new covariance matrix designs and the well-known multi-antenna radar designs including phased-array,MIMO radar and phased-MIMO radar *** is shown that Binary Phased-Shift Keying(BPSK)waveforms that have constant envelope can be used in a closed-form to realize the proposed covariance ***,there is no need to deploy different types of radio amplifiers in the transmitter which will reduce the cost,*** proposed design allows the same transmit power from each antenna in contrast to the phased-MIMO ***,the proposed covariance matrix is full-rank and has the same capability as MIMO radar to identify more targets,*** of the proposed transmit covariance matrix including receive beampattern and output Signal-to-Interference plus Noise Ratio(SINR)is simulated,which validates analytical results.
