摘　　要：设计可用于调幅射频电磁场生物效应研究的人体辐照平台,分别从硬件系统部分和软件系统部分两方面进行介绍。硬件系统由射频信号发生模块、功率放大模块、阻抗匹配模块以及发射天线构成,其接收到由软件系统发出的载波、调制频率、调制深度以及功率参数指令后,进而实时产生相应的调幅射频电磁场。实际测量结果表明,设计的调幅射频电磁场人体辐照实验系统具有良好的性能参数,该系统为人体调幅射频电磁场生物效应研究提供一个使用方便、参数可控的电磁辐照平台。A human body irradiation experimental system used for studying biological effects of amplitude-modulated radiofrequency electromagnetic field was designed. The system are introduced in the aspects of hardware system and software system respectively. The hardware system which is composed of radiofrequency signal generating module,power amplification module,impedance matching module and transmitting antenna receives parameter instructions of carrier wave,modulation frequency,modulation depth and power issued by the software system,and then generates the corresponding amplitude-modulated radiofrequency electromagnetic field in real time. The actual measurement results show that the designed human body irradiation experimental system for amplitude-modulated radiofrequency electromagnetic field has good performance parameters,and can provide an easy-to-use and parameter-controllable electromagnetic irradiation platform for biological effect research on human body amplitude-modulated radiofrequency electromagnetic field.
