Method and system for detecting extraterrestrial solid star structures using one-shot, multiple-receive radar

Abstract

A method for detecting the geological structure of extraterrestrial solid stars by using one-shot-multiple-receive radar. In this method, the detection of the thickness distribution and structure of each geological layer of extraterrestrial solid stars is completed by using the working mode of one send and multiple receivers, and the dielectric constant, depth and other information of each geological layer are retrieved by using the theory of electromagnetic wave propagation. It has the advantage of high reliability. An ultra-wideband carrier-free pulse radar system for detecting geological structures of extraterrestrial solid stars is also announced. In this system, two detection channels are used. The CH1 detection channel works in the HF / VHF band and is used for rock structure detection of stars. The detection depth is greater than 100 meters and the resolution is meter level; the CH2 detection channel works in the UHF band. For the detection of shallow soil structure of stars, the detection depth is greater than 30 meters, and the resolution is less than 30 cm. The two detection channels work together to complement each other, which can ensure the accuracy and reliability of the detection work.

Description

technical field [0001] The invention relates to the field of radar technology in the electronic industry, in particular to a method and system for detecting geological structures of extraterrestrial solid stars by using the one-shot-multiple-receive radar technology. Background technique [0002] Since the end of the 1950s when humans mastered the technology of entering space, countries such as Europe and the United States have carried out a series of exploration studies on extraterrestrial bodies including the moon, Mars, Venus, and Jupiter. However, humans still know little about the geological structure and soil thickness distribution inside extraterrestrial bodies. Humans also need to develop more advanced detection instruments to detect the soil and rock geological structure of extraterrestrial bodies, to study the topography of extraterrestrial bodies, to estimate the content of mineral resources, and to study the formation and evolution history of extraterrestrial bod...

AI Technical Summary

Problems solved by technology

These radars can only assume the value of the dielectric constant in advance to calculate the subsurface layer depth of the moon or Mars, which has a large error

In addition, the radar systems that have been used to detect the subsurface structure of the moon and Mars are all installed on orbital probes in the outer space of the moon or Mars. Due to the limitation of equipment installation space and detection technology, the working bandwidth is narrow, and the resolution of detection results is relatively high. Low, cannot detect the soil layer structure and soil thickness distribution of the moon or Mars
