Additional degree of freedom in phased‐MIMO radar signal design using space‐time codes
ETRI Journal, 2021 In this paper, an additional degree of freedom in phased multi‐input multi‐output (phased‐MIMO) radar with any arbitrary desired covariance matrix is proposed using space‐time codes. By using the proposed method, any desired transmit covariance matrix in
