Abstract—

Investigations of the Solar System with space missions yielded a significant volume of data on geophysical and morphological properties of planets. On this basis, a new research area, comparative planetology, was developed. It is focused on the description of natural phenomena occurring on celestial bodies rather than only the formulation of evolutionary and cosmogonic concepts. The purpose of the present study is to analyze a digital model of the physical surface of the Moon, which is based on the measurements carried out in the course of the Kaguya space mission. To construct and analyze this model, we use a multiparameter harmonic analysis of the optical and altimetry data obtained during spaceborne observations near the Moon. We develop an approach that includes the construction of regressive harmonic models in terms of the altimetry data expansion and the analysis of their fractal dimensions. For the considered system, a spectrum of fractal estimates has been obtained for both different local zones and an entire model of the lunar sphere.

月球的物理表面:基于卫星测高仪的数字模型

摘要-

对具有太空任务的太阳系的研究产生了大量有关行星地球物理和形态特征的数据。在此基础上,开发了一个新的研究领域,比较行星学。它着重于描述天体上发生的自然现象,而不仅仅是对演化和宇宙概念的表述。本研究的目的是分析月球物理表面的数字模型,该模型基于在Kaguya过程中进行的测量太空任务。为了构建和分析该模型,我们对月球附近太空观测中获得的光学和测高数据进行了多参数谐波分析。我们开发了一种方法,其中包括根据测高仪数据扩展及其分形维数分析构建回归谐波模型。对于考虑的系统,已经获得了不同局部区域和月球整个模型的分形估计谱。
