针对固态高功率微波系统对快上升沿窄脉冲的需求,对脉冲上升沿的影响因素进行了原理分析,提出了基于光子合成的快上升沿脉冲信号产生方法,并利用微波光子链路带宽大和带内一致性好的优势,研制了基于光子合成的纳秒量级上升沿脉冲信号产生样机,并对该样机进行了性能指标和波形产生测试试验。实验结果表明,所研制样机产生的脉冲上升沿达到纳秒量级,可生成非线性调频、相移键控(phase shift keying,PSK)和频移键控(frequency shift keying,FSK)等复合调制波形,可为固态体制高功率微波系统的多功能实现提供技术支撑。

A fast-rise-edge pulse signal generation method based on photon synthesis is proposed,and a nanosecond level edge pulse signal prototype based on photon synthesis is developed.The output signal pulse width and edge of the prototype reach the nanosecond level,and the waveform modulation mode is optional.Performance indicators and waveform generation tests are conducted on the prototype,and the experimental results show that the pulse edge generated by the developed prototype reached 1ns,which can generate complex modulation waveforms such as nonlinear frequency modulation phase shift keying(PSK)and frequency shift keying(FSK),providing technical support for the multifunction implementation of solid-state high power microwave systems.
