CLEAN Receiver for CDMA MIMO Radar

Implementation of the intra-coding code-division multiple access (CDMA) multiple-input multiple-output (MIMO) radars requires orthogonality between the transmitted codewords. The lack of complete orthogonality between practical codewords induces sidelobes in the received signal which mask weak targets and increase probability of false alarm (PFA). This work proposes a novel and efficient CLEAN CDMA-MIMO approach, which considers all the transmitted codewords and the receiver noise coloring. The performance of the proposed approach is evaluated via simulations of a practical automotive scenario.
