Design and Implementation of an On-Orbit Information Processing System for In-Situ Detection of Spaceborne Micro-Debris

With the rapid increase in the amount of space debris, millimeter-scale microparticles pose a serious threat to spacecraft safety. In response, this study designs and implements an onboard microparticle detection system, which utilizes the piezoelectric sensing principle to achieve multi-channel real-time signal acquisition and processing. The system employs a joint FPGA-MCU architecture, integrating adaptive filtering and event recognition algorithms. Ground-based simulation experiments have verified the system’s effective detection capability for microparticles, demonstrating high stability and strong potential for engineering applications.
