摘要
月球重力场探测是了解月球内部结构构造最有效的手段之一,也是未来登陆点选择的重要依据。在众多方法中,卫星重力探测是进行全月球覆盖以及获得月球深部信息的重要方法。本文叙述了当前月球重力探测历史和重力模型发展过程,并对这些模型进行比较分析。在了解前沿研究方法的基础上讨论了月球重力位场解算的基本原理、高精度月球重力场获得的方法和各种月球重力归算方法,以及当前国际上利用月球重力场研究其内部结构构造的热点问题。最后对月球的典型重力异常特征进行了综合性的分析。
Lunar gravimetry is one of the most useful approaches to understanding the interior constitution and structure of the moon and also serves as a fundamental basis for choice of landing sites in future. Of varied methods, satellite gravimetry is an important means for covering the whole moon and obtaining deep information. This paper has described the history of lunar gravity exploration and the development of lunar gravity models, and analyzed and comparatively studied these models. Based on knowledge of forefront research methods, the authors deal with the principle for solution of lunar gravity coefficient model, approaches to acquiring lunar gravity model with high accuracy, varied tools for gravity field reductions, and current heated topics in the study of the interior structure of the moon. In addition, characteristics of typical gravity anomalies in the moon are comprehensively analyzed.
