摘　　要：针对多输入多输出(MIMO)雷达波束设计问题,提出一种基于峰均功率比(PAPR)的单级传输波速-形成设计方法。首先,将MIMO雷达波束图型匹配问题公式化;然后,通过幂迭代有效处理PAPR约束,并计算权重矩阵和发射信号矩阵;最后,考虑用于系统模型的发射波束域,利用迭代完成MIMO雷达波束设计。数值实例分析结果表明,相比两级传输方法CMS,本文方法的信号具有较好的模糊度属性,在大型网格波束图型匹配方案中的计算负载显著减小。For the issue of MIMO radar beam forming designing, a single stage transmission beam forming desig_ning method based on peak to average power ratio is proposed. Firstly, the MIMO radar beam pattern matching prob_lem is formulized. Then, power iteration is used to effectively handle PAPR constraints and the weighting matrix and transmitting matrix is calculated. Finally, iteration is used to finish the MIMO radar beam design considering beam do_main applied in launch of the system model. The numerical example analysis results show that proposed method has better attribute of fuzzy degree than double stages transmission method CMS, and it greatly reduces the computational load in large grid beam pattern matching scheme.
