摘　　要：低地球轨道(LEO)空间环境与效应给低轨航天器带来严重威胁,因此需要对LEO空间环境和效应进行监测。文章提出LEO空间环境与效应集成化监测的设计思路,从电子电路设计、监测载荷设计和结构总体设计3方面给出了针对电子、质子、原子氧、温度、总剂量、表面电位、污染等环境与效应的监测方法以及集成化设计方法,可以实现瞬时参数(通量、剂量率、污染沉积率)和累积参数(注量、累积通量、总剂量、总污染量)的监测。The space environments and their effects in the low Earth orbit(LEO)pose a serious threat to the LEO spacecraft,therefore,it is necessary to monitor the related environments and their effects.This paper proposes an integrated design of the environmental monitoring device onboard the LEO spacecraft.The design is explained from the aspects of the electronic circuit integration,the corresponding payload design,and the structural optimization,in view of its capability of monitoring the electron&proton irradiation,the atomic oxygen,the local temperature,the surface potential,the total dosage,and the contamination.The instantaneous parameters(flux,dose rate,contamination deposition rate)as well as the cumulative parameters(fluence,total dosage,total contamination level)can be monitored simultaneously.
