摘　　要：传统的微波信号频率的测量方法主要采用电子器件实现,结构复杂,体积大,且受模数转换器(ADC)的模拟输入频率范围等限制,无法直接对宽带的射频信号进行频率测量。针对复杂电磁环境下宽带射频信号频率测量的问题,提出了一种基于色散介质与光纤光栅的宽带微波光子频率测量方法,从仿真的角度研究了色散系数、色散长度、光载波波长等对宽带频率测量的影响,仿真结果表明该方法可以实现对宽带微波信号频率的测量。Traditional measurement methods of microwave signal frequency are mainly implemented though electronic devices,which are complex in structure,large in volume,and limited by the analog input frequency range of analog-digital converter(ADC),etc.,and can’t directly measure the frequency of wide band radio frequency signals.Aiming at the problem of frequency measurement for wide band radio frequency signals in the complex electromagnetic environment,this paper proposes a frequency measurement method for wide band microwave photon based on dispersive medium and fiber grating,studies the influence of dispersion coefficient,dispersion length,optical carrier wavelength,etc.on wide band frequency measurement from the perspective of simulation.The simulation results show that this method can achieve the frequency measurement of wide band microwave signal.
