摘　　要：当接收天线工作于扫描模式时,不同脉冲重复频率的高功率微波进入接收天线主瓣的有效脉冲个数耦合效率差异较大。针对该问题,通过分析发射脉冲间隔角度的稳态形式,建立了接收天线分别工作于周扫和扇扫模式时计算有效脉冲个数耦合效率的数学模型。对典型情况进行分析,给出了最小有效脉冲个数比例高且时间周期短时所需的最低重复频率。The number of effective pulses of high power microwave(HPM)with different pulse repetition rates entering the main lobe of the receiving antenna varies greatly when the receiving antenna works in the scanning mode.By analyzing the steady state of the interval angle of the transmission pulse,a mathematical model is established to calculate the effective number of pulses when the receiving antenna operates in the circular scanning mode and the fan scanning mode,respectively.The minimum repetition frequency with high proportion of effective pulse numbers and short time period is given by analyzing the typical case.
