【摘要】：火星已经成为深空探测的重要目标之一,登陆火星并在火星生存是人类探测火星的终极目标,因此电离层是必须了解的火星电磁环境.火星电离层探测包括直接探测和间接探测.直接探测精度高,有较高的空间分辨率,但是观测时间短,无法提供长期稳定的探测结果.对火星电离层的间接探测结果主要来自无线电掩星探测和顶部雷达探测.无线电掩星探测可实现对火星电离层整个电子密度剖面的长期稳定探测,但其空间水平分辨率较低,且可探测的电离层太阳天顶角范围受到地球与火星轨道的限制.顶部雷达探测对火星电离层的探测具有很高的时间分辨率和空间分辨率,且同样可进行长期稳定探测,为火星电离层研究提供了最新的支持.通过对火星电离层探测的基本方法及典型观测结果的分析,提出通过几种探测方法适当结合的方式,同时对火星电离层进行观测,能够大大推进对火星电离层的研究.
[Abstract]:Mars has become one of the important goals of deep space exploration, Mars and Mars in life is the ultimate goal of human exploration of Mars, the Mars ionosphere is the electromagnetic environment must be aware of the Martian ionosphere detection including direct detection and indirect detection. The direct detection of high precision, high spatial resolution, but the observation time is short, can not provide detection the long-term stability of the Martian ionosphere. Indirect detection results mainly from radio occultation detection and radar detection. The top radio occultation experiments can achieve long-term stability of the Martian ionosphere electron density profile detection, but the level of spatial resolution is low, and can detect the ionospheric solar zenith angle range by the earth and Mars orbit. With very high temporal and spatial resolution of the detection of the Martian ionosphere top radar detection, and also can The long-term stable detection, provides the latest support for Mars ionospheric research. Through the analysis of the basic methods of Mars ionosphere detection and typical observation results, several detection methods proposed by appropriate combination of simultaneous observations of the Martian ionosphere, can greatly promote the research of the Martian ionosphere.
