摘要: 为获取某型高功率微波辐射系统辐射至空中靶目标处(数十m至数百km处)的微波脉冲参数，基于某升空平台无线数传链路，设计了一种结构简单、紧凑的远程无线高功率微波辐射场测量数据采集系统。该系统具备运行状态动态指示、测量参数远程设置以及波形数据实时显示等功能，质量小于2 kg，瞬时动态范围大于15 dB。试验结果表明：测量系统具备高重频微波脉冲参数测量能力，能实时有效捕获辐射场微波波形，运行稳定可靠，可满足百km级距离上的空中辐射场测量需求。Abstract: In order to detect microwave pulse parameters at aerial target areas (tens of meters to hundreds of kilometers)of a certain type high power microwave radiation system, a data acquisition system whose structure is simple and compact for high power microwave remote measurement is designed base on wireless remote data transmission link of aerial flying platform. The system can display running state dynamically, set measuring parameter remotely and display waveform in real time. What's more, the weight of the system is less than 2 kg and the dynamic range of the system is more than 15 dB. Our experiments show that the system can measure high repetition frequency microwave radiation field. It meets the requirement of aerial microwave radiation field measurement at hundreds of kilometers distance. It also lays the foundation for the design of microwave radiation field measurement systems at higher and farther distance in the future.
