Resolution of two point targets using sub-arrayed MIMO radar

Recent works on MIMO radar have shown benefits in optimising the signal covariance matrix for estimation of target parameters, over the performance of conventional radar and the orthogonal waveform approach used in much of the MIMO radar literature to date. The full diversity approach requires a large amount of flexibility at the transmitter and computation prior to transmission. In this work, we study the performance of a sub-arrayed transmit beamforming approach for MIMO Radar, which greatly reduces the requirements of the transmitter, for the important case of resolving two point targets.
