摘要 多输入多输出(MIMO)雷达是近年雷达领域研究的热点之一,国内外专家对MIMO雷达的认识也存在模糊的地方。MIMO雷达计算复杂度高,特别在阵元数量较多的情况下更为明显,所以工程上在米波频段更容易实现MIMO雷达。基于米波MIMO雷达系统设计的角度,并从MIMO雷达工作物理理解结合理论分析,对其独特的功率孔径资源设计、低空探测性能、抗干扰能力和测高精度四个关键问题进行分析。米波MIMO雷达具有明显的技术特点,最后对部分结论进行了试验验证。 MIMO radar is one of the research hotspots in international radar community. Both domestic and foreign professionals are controversial on the performance of MIMO radar. As far as the high.computation complexity of MIMO radar, especially in large amount of array elements, the VHF MIMO radar has its advantage in engineering realization. Based on the system design and the physical meanings of MIMO radar, the power-aperture resource design, low-altitude detection capability, anti-interference and height measurement of the VHF MIMO radar are analyzed. The VHF MIMO radar has obvious technical features. Finally, some experimental results are given.
