摘　　要：为解决传统的多模式目标源结构复杂且成本高昂的问题,提出了一种利用拍频调制技术实现微波信号、红外信号和激光信号产生的三模式目标模拟系统。利用光外差法可实现微波信号的产生,通过任意波形发生器加载调制信息可实现微波信号频率、波形、重频和脉宽的调制;利用激光信号和红外信号转换模块可实现激光信号到红外信号的转换;通过调节激光信号的输出功率可实现红外信号的温度调谐。利用种子源激光器产生激光信号,通过任意波形发生器和调制器可实现带有调制信息的激光信号产生,产生的微波信号频率最高可达40 GHz,同时可产生温度达230℃的红外信号和带有10 Gbps调制信息的激光信号。该目标源模拟系统可实现微波信号、红外信号和激光信号三种发射模式,且主要采用光纤器件组成,具有成本低廉、结构简单、抗干扰能力强的优点。In order to solve the problem of complex structure and high cost of traditional multi-mode target source,three-mode target simulation system for generating microwave signal, infrared signal and laser signal using beat frequency modulation technology is proposed in this paper. The microwave signal can be generated by optical heterodyne method, and the modulation information can be modulated by the arbitrary waveform generator to achieve the microwave signal with different frequency, wave, repetitive frequency and pulse width. The laser signal and infrared signal conversion module can be used to convert the laser signal to the infrared signal, and the temperature tuning of the infrared signal can be achieved by adjusting the output power of laser signal. The seed source laser is used to generate the laser signal,and the laser signal with modulation information can be generated through the arbitrary waveform generator and the modulator. The generated microwave signal can reach up to 40 GHz, at the same time, it can generate infrared signals with the temperature of 230℃ and laser signals with 10 Gbps modulation information. The target source simulation system can realize three emission modes of microwave signal, infrared signal and laser signal. Furthermore, the structure is mainly composed of optical fiber devices, which has the advantages of low cost, simple structure and strong anti-interference ability.
