Based on the MIMO idea and the circular array radar, the meter-wave circular radar for MIMO systems is proposed. For the meter-wave circular array radar using MIMO systems, the correlation between the target and the image is reduced, the effective aperture of virtual array is also increased, and the two-dimension angles of the target and the image can be estimated. Theory analyses and simulation experiment results show that the meter-wave circular array radar for MIMO systems not only can obtain the azimuth angle of the target, but also can make the differentiation between the target and the image from the elevation.
