Embodiment Construction

[0045] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments disclosed in the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0046] Such as figure 1 and figure 2 , in this embodiment, the method for simulating the surface morphology of Mars under the earth environment includes:

[0047]Step 101, constructing and obtaining the base terrain for simulating the distribution of bases and fire pits on the surface of Mars.

[0048] In this embodiment, the specific construction process of the basic terrain is as follows:

[0049] (11) Excavate to a certain depth h from the ground 1 pit.

[0050] In this embodiment, the size of the pit can be set according to the actual situation, for example, the depth h of the pit from the ground 1 500mm, the length of the pit is 60m, and the width is 60m.

[0051] (12) Excavate a certain depth h below the pit 2 ditches, la...

Abstract

The invention discloses a method for simulating the surface morphology of Mars in an earth environment. The method comprises the following steps: constructing a basic terrain for simulating the surface morphology of Mars; based on the basic terrain, constructing a first simulated Mars surface morphology with different Mars pit distribution characteristics; based on the first simulated Mars surface morphology, constructing a second simulated Mars surface morphology with different Mars pit distribution characteristics and Mars rock distribution characteristics; based on the second simulated Mars surface morphology, constructing a third Mars surface morphology with different Mars pit distribution characteristics, Mars rock distribution characteristics and fire slope distribution characteristics; and based on the third Mars surface morphology, constructing a simulated Mars surface morphology which has different Mars pit distribution characteristics, Mars rock distribution characteristics and fire slope distribution characteristics and can reflect Mars surface microwave and aurora reflection characteristics. The invention aims to realize the real representation of the Mars surface topography and landform, and ensures that the Mars lander can identify the Mars surface morphology (Mars pit, Mars rock, Mars slope and the like) with high precision in the Mars surface landing process.

Description

technical field [0001] The invention belongs to the technical field of spacecraft recovery landing and low-gravity extraterrestrial celestial body landing test, and in particular relates to a method for simulating the surface form of Mars under the earth environment. Background technique [0002] With the rapid development of aerospace technology, the exploration of extraterrestrial planets has become one of the important directions for human beings to explore the universe. Among them, the Mars exploration project has completed the content of the experimental stage and entered the substantive implementation stage. The gravity of Mars is only 38% of that of Earth, the air density is only 1% of that of Earth, and the terrain is special, so the difficulty of landing is self-evident. The surface of Mars is full of gravel, and at the same time, it is full of potholes formed by impacts after being attacked by meteorites, and there are slopes of various slopes, which seriously thre...
