Transmit Signal and Receive Filter Design in Co-located MIMO Radar Using a Transmit Weighting Matrix

In this letter, we jointly design the transmit signals and the receive combining filter based on exact information on the locations of target and interferences in co-located multiple-input multiple-output (MIMO) radars. The idea behind the proposed method is to maximize the signal-to-interference-plus-noise ratio (SINR) without designing the waveform covariance matrix and exploit the advantages of MIMO radar. Each transmit element sends linear combinations of the orthogonal waveforms by a weighting matrix. Numerical results show the improvement in the SINR performance offered by using the proposed algorithm compared to the phased array and existing MIMO radar techniques.
