摘要
为了对密集阵MIMO雷达不同阵列模式之间的联系进行研究,建立了密集阵MIMO雷达多次快拍信号模型,导出了接收信号相位历史的解析表达式,并通过相位历史表达式揭示了其蕴含的三种阵列模式以及生成机理;结合各阵列模式形成机理分别讨论了三种不同模式阵列特性.最后通过仿真结果对各阵列模式的特性进行了分析.研究结果表明,密集阵MIMO雷达不同阵列模式可带来不同的得益.
In order to reveal the links of various array modes of MIMO radar with dense mode（DM） arrays this paper sets up a model of multiple snapshot signals of the MIMO radar,and derives the analytic expression of the phase history of the received signals.By analyzing the expression,three contained array modes and generation mechanism are illuminated,and based on the mechanism of each array mode,three sorts of array characteristics with different modes are discussed.And finally,by simulation,the characteristics of various array modes are analyzed in this paper.The results of study show that the various array modes of the MIMO radar with DM arrays can bring about different benefits and gains.
