摘要:
日本SELENE/KAGUYA探测任务提供了研究月球电离层的机会。采用无线电掩星探测技术和趋势外推算法,消除地球电离层和行星际等离子体的干扰影响,残余的信号相位信息的变化反映了月球电离层的信息,估算出月球周围附近近似对称分布的稀薄电离层中电子总含量(TEC)约为每立方米10-14个。

Abstract:
To measure the thin plasma layer above the surface of the moon, via using radio occultation technique and coherent radio waves of the S/X-band, dual-frequency measurements could be acquired at a given Earth-based receiving station. On the line-sight direction, the terrestrial ionosphere, interplanetary plasma and thin lunar ionosphere are mixed together, in order to investigate the relatively pure variation of ionospheric total electron content (TEC) surrounding the moon. Using the trend extrapolation method, the terrestrial ionosphere and interplanetary disturbance error influence could be eliminated, so as to estimate the fitting trend component. The TEC of lunar ionosphere is obtained about ~10-14 /m2, after subtracting this trend component from the original observation data obtained at the tracking station.
Key words:  unar ionosphere;total electron content;radio occultation
