Problems solved by technology

[0004] However, in the process of realizing the present invention, the applicant found that: the neutron spectrum obtained by the neutron measurement technique cannot distinguish the different chemical forms of hydrogen, so using this method cannot obtain definite evidence of the existence of subsurface ice, and cannot determine ice thickness

Abstract

The invention provides a method for detecting a Mars underground ice layer by use of a double-frequency radar. According to the method, through analyzing characteristics including radar echo signal intensity and time-delay and the like, information such as the thickness of the cover layer on the surface of the Mars, whether the ice layer exists underground on the Mars, the thickness of the ice layer and the like can be obtained. Compared to a neutron measuring technology in the prior art, the accuracy and reliability are higher.

Description

technical field [0001] The invention relates to the technical field of radar detection in the electronic industry, in particular to a method for detecting underground ice layers by using a dual-frequency radar. Background technique [0002] Ice in which water or meltwater has solidified at low temperatures is called an ice sheet. On Earth, the most common ice formations are summer falls turning into winter ice falls, which are seasonal ice walls. On extraterrestrial celestial bodies such as the moon and Mars, there are also a large number of ice layers. According to observations, a large number of "water pockets" with ice layers have been found at the north pole of the moon, which provides another optional research area for the possible lunar exploration activities of the unmanned astronaut probe. The discovery of ice on a cosmic body is an exciting discovery that could provide a natural resource for future astronauts on moon landing missions. And it can be melted into dr...
