摘要: |
将MIMO(Multiple Input Multiple Output)思想和圆阵雷达结合起来,提出了MIMO体制的米波圆阵雷达模型。对于米波圆阵雷达,采用MIMO体制后,目标和镜像的相关性减弱,虚拟阵列的有效孔径增大,能实现目标和镜像的二维角估计。理论分析及仿真实验结果表明,MIMO体制的米波圆阵雷达不仅能估计出目标的方位角,且能从俯仰上将目标和镜像分开。 |

Abstract: |
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. |
