    Antenna beam pattern in MIMO radar systems, like any other radar, exhibits sidelobes. Naturally it is possible for clutter and other sort of interference to be detected accidently via these sidelobes. This has the effect of mis-aligning the main beam steering vector and reducing detection performance. In addition, the performance is dependent on the precision of the array calibration process. This... View full abstract»
