| Abstract: | To further study the characteristics of plasma sheath and its influence on electromagnetic wave transmission,the project developed a multi-dimensional characteristic measurement system for plasma electromagnetic signals,the system can be used to measure the multi-dimensional characteristic of communication signals under high-speed target plasma,analyze signal attenuation,phase distortion and other characteristics.The system has completed the plasma transmission measurement experiment in Ka frequency band,which verifies the capability of the multi-dimensional feature measurement system for broadband measurement and detection of large dynamic weak signals.The collected data were analyzed,and the influence of plasma on the attenuation and phase characteristics of communication signal was preliminarily verified. |
