摘　　要：针对机载相控阵PD雷达波束宽度随扫描角变化的特点,详细阐述了中脉冲重复频率(MPRF)设计与选择的具体方法步骤。从M/N准则选择、重频范围2方面确定深入研究了MPRF设计问题;从优化模型、约束条件、优化算法3方面深入探讨了MPRF选择问题,提出利用可调参数少、收敛速度快、全局寻优能力强的粒子群算法选择最优MPRF。最后通过具体实例说明了机载相控阵PD雷达MPRF设计与选择方法的有效性。The detailed methods and steps of medium pulse repetition frequency（MPRF） design and selection are described based on the characteristics of phase array radar. The MPRF design problem is analyzed from M/N scheme selection and the pulse recurrence frequency（PRF） range, and The MPRF selection problem is discussed from three aspects of optimization model, constraints and optimization algo- rithm. Swarm optimization algorithm is developed to select optimum MPRF, for the algorithm has simple realization process, less adjustable parameters, higher convergence speed and stronger global optimiza- tion. Finally, an example is given to demonstrate the effectiveness of the proposed MPRF design and selection method.
