摘　　要：分集多输入多输出(MIMO)雷达利用目标的空间散射多样性克服由于目标雷达散射截面积闪烁引起的漏警,为隐身目标有效探测提供解决办法。分集MIMO雷达布站方式对性能影响很大,文中以相控阵体制雷达为研究对象,研究其组成分集MIMO雷达时的规模、站间距、单站威力差异约束和布站方式等,并通过蒙特卡罗仿真给出了布站建议。Diversity multiple-input multiple-output (MIMO) radar can use target scattering diversity to overcome leaking-detecting caused by RCS scintillation. It provide a solution for the detection of stealth target, but the performance depends largely on the disposition. This paper takes phased-array radar as the research object and give the proposal of disposition through studying of the scale, spacing, difference of power and so on.
