Embodiment Construction
[0029] Specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0030] According to the topography of the lunar surface, the present invention constructs a typical moon appearance of the landing site on the lunar surface in the range of 60m×60m, simulates the visual environment such as the moon shape and moon appearance close to the real shape of the moon surface, and satisfies the general reflection of the detector on visible light, radar and laser Require. Provide a lunar-like detection environment for the detection equipment carried by the lunar probe, so as to assess and verify the lunar surface recognition ability of the probe.
[0031] Such as figure 1 As shown, a method for simulating the surface characteristics of the moon of the present invention comprises steps as follows:
[0032] (1) Determining the building materials for making the lunar surface: first, a certain ratio of building ma...

The invention discloses a method for simulating surface characters of the moon. The method includes the following steps that building materials for making moon topographic features are determined; coating for making the surface layer of the moon topographic features is determined; base moon topographic features are determined; a moon surface character simulation foundation with a certain size and thickness is laid using the determined building composite materials; a drainage pipeline is structured under each position of the corresponding lunar crater on the moon surface character simulation foundation according to the determined base moon topographic features; the base moon topographic features on the moon surface character simulation foundation are sculpted according to the determined base moon topographic feature; removable characters on the moon topographic features are sculpted using the building composite materials with a determined recipe; the moon surface character simulation foundation and the removable moon topographic feature characters are coated with a certain thickness by the determined coating; the removable characters are moved, and the moon topographic feature characters with different arranging conditions are obtained. A probing environment similar to the moon is provided, and the assessment of moon topographic feature recognition capability of a probe is achieved.
Description
technical field [0001] This patent belongs to the field of spacecraft ground tests, and relates to a method for simulating the characteristics of the lunar surface. Background technique [0002] There are craters of different sizes and gravel blocks of various sizes on the surface of the moon, and the distribution is uneven. In a high vacuum environment, after a long period of bombardment by meteorites and micrometeorites, floating soil without organic matter is formed. The soil layer from the surface to several meters deep is composed of gravel and fine dust of various sizes. This is an unfamiliar physical state. Therefore, compared with the topographic features of the earth's surface, the moon's appearance is very different. It is one of the core issues that the probe must consider when landing on the moon. [0003] For visible light with a wavelength of 600nm to 800nm and laser light with a wavelength of 1047nm to 1064nm, the albedo range of the simulated area on the ...
