航天飞行器机载传感器信号调理技术应用与实践OA

This paper elucidates the critical role of on-board sensors in the design,development,and application of aerospace vehicles.It introduces the sensitive elements of conventional on-board sensors(e.g.,strain gauges)and outlines the essential requirements for designing corresponding signal conditioning circuits.Schematic designs for typical sensor signal conditioning circuits,including those for charge signals,are presented.Furthermore,common signal conditioning schemes,such as anti-aliasing filtering,along with their expected performance,are discussed.The paper also addresses practical issues encountered during the engineering application of this technology in aerospace vehicles,proposing corresponding countermeasures and evaluating their effectiveness.The primary objective of applying signal conditioning technology is to maximize the fidelity of the restored sensor signals.Extensive engineering practice will continuously consolidate the technical foundation for signal acquisition and processing of on-board sensor arrays in aerospace vehicles.
