“…Recently, the concept of observing the Earth from the Moon-based platform was proposed [2][3][4]. The Moon, as the Earth's only natural satellite, is stable in periodic motion, making an onboard sensor unique in observing large-scale phenomena that are related to the Earth's environmental change [5,6]. Synthetic aperture radar (SAR), an active sensor, provides effective monitoring of the Earth with all-time observation capabilities [7,8].…”

“…Also, the concept of the Moon-based Interferometric SAR (InSAR) were analyzed by Renga and Moccia [4]. Later, the performance and potential applications of the Moon-Based SAR were characterized by Moccia and Renga [5], and the scientific and technical issues in the application of lunar-based repeat track and along track interferometry in [6]. Following this stream of development, an L-band Moon-Based SAR for monitoring large-scale phenomena related to global environmental changes was discussed [9] and the coverage performance of the Moon-based platform for global change detection [10].…”

Abstract:The Moon-based Synthetic Aperture Radar (Moon-Based SAR), using the Moon as a platform, has a great potential to offer global-scale coverage of the earth's surface with a high revisit cycle and is able to meet the scientific requirements for climate change study. However, operating in the lunar orbit, Moon-Based SAR imaging is confined within a complex geometry of the Moon-Based SAR, Moon, and Earth, where both rotation and revolution have effects. The extremely long exposure time of Moon-Based SAR presents a curved moving trajectory and the protracted time-delay in propagation makes the "stop-and-go" assumption no longer valid. Consequently, the conventional SAR imaging technique is no longer valid for Moon-Based SAR. This paper develops a Moon-Based SAR theory in which a signal model is derived. The Doppler parameters in the context of lunar revolution with the removal of 'stop-and-go' assumption are first estimated, and then characteristics of Moon-Based SAR imaging's azimuthal resolution are analyzed. In addition, a signal model of Moon-Based SAR and its two-dimensional (2-D) spectrum are further derived. Numerical simulation using point targets validates the signal model and enables Doppler parameter estimation for image focusing.

“…Given that one satellite typically has only one or two sensors onboard, is it too luxurious to design, build, launch and maintain individual payload platforms? Beside the audacious ambition of using the moon as one Earth observing platform (Guo et al, 2014a;Moccia and Renga, 2010;Fornaro et al, 2010), is there any other efficient way for us to remotely observe our planet from space?…”

“…Afterwards, Italian scientist Moccia [2] and G. Fornaro [3] separately calculated systematic parameters of lunar-based SAR for the application of Interferometry and discussed the long integration time and the mechanism of lunar-based InSAR. Moccia proposed a goal which is high spatial and temporal resolution mapping lunar-based InSAR, comparing the system performance of swath and beaming mode, finally analyze the factors that influence the accuracy of lunarbased monorail double antenna interference mapping.…”

With several advantages superior to low earth orbit SAR, such as high space resolution together with large range swath and short revisit interval, the moon based SAR (MB-SAR) could be a potential data source for global changes monitoring and environment change research. Due to the high stability and ease of maintenance, the novel system is competent for offering a long and continuous time series of remote sensing imagery. In this paper, we discuss the system performance briefly at the beginning, and next focus on its possible applications.
