Target DOA Estimation using GLRT and Crosstalk Reduction for MIMO Radar

Multiple-Input Multiple-Output (MIMO) radars with colocated antennas have been shown to have higher resolution and better accuracy in target localization than standard phased-array radars. However, due to the proximity of the antenna elements, direct coupling between the transmitters and the receivers (crosstalk) may exist and degrade in the narrowband case the performance of some detection techniques, such as the Generalized Likelihood Ratio Test (GLRT) based one. This paper presents a crosstalk reduction technique for MIMO radar
