Research on Integrated Sensor Technology of Electrostatic Discharge Ultrasonic and High-Frequency Electromagnetic Wave for Spacecraft Space Equipment

During orbital operation, the space plasma environment affects the spacecraft, leading to the occurrence of electrostatic discharge, which can jeopardize the safe operation of the spacecraft. To enable easy, accurate, and reliable electrostatic discharge detection, this article proposes an integrated electrostatic discharge sensing method that leverages ultrasonic and electromagnetic radiation. The developed integrated sensor has the ability to detect ultrasonic and high-frequency electromagnetic wave signals generated by electrostatic discharge, and a space plasma charging effect simulation platform is built to verify the integrated sensor detection of spacecraft electrostatic discharge. The experimental results demonstrate that the integrated sensor developed in this article can sense both ultrasonic and high-frequency electromagnetic wave signals generated by electrostatic discharge. The research findings of this article hold significant implications for the effective and efficient perception of the electrostatic discharge power supply of spacecraft.
