针对分布式MIMO雷达目标检测问题,该文首先根据分布式MIMO雷达站间的位置几何分布,给出了分布式MIMO雷达系统的3种形态:分布式相参MIMO雷达、相位随机MIMO雷达和幅相随机MIMO雷达。然后重点推导了低信噪比条件下相位随机和幅相随机MIMO雷达的平方律检测器结构,并详细分析了这两种检测器的检测性能。最后的仿真实验说明了该文的理论分析对实际工程具有一定的指导意义。
To address the problem of target detection in distributed MIMO radar, three styles of distributed MIMO radar systems are given in this paper. With respect to the geometric distribution relations of distributed MIMO radar, the styles are distributed coherent MIMO radar, random phase MIMO radar, and random amplitude-phase MIMO radar. Next, the square law detector structures of random phase and random amplitude-phase MIMO radar are derived in the paper when there is a low signal-to-noise ratio, and the performance of the two detectors are analyzed as well. Finally, simulation results demonstrate the theoretical analysis of this paper are of guiding significance for the actual engineering.
