SINR maximization in colocated MIMO radars using transmit covariance matrix
We proposed two covariance matrices in order to maximize the signal-to-interference-plusnoise ratio (SINR) and to exploit the advantages of MIMO radars. Two proposed matrices are full rank to suppress more interferences. Maximum achievable SINR is calculated analytically for both. Using these matrices enables us to transmit BPSK samples with the same covariance matrix. The second proposed matrix has a low side lobe level and therefore has a good performance in the case of unknown interference location.
