It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] The present invention provides a mineral exploration system, which is described below.

[0036] FIG1 is a schematic structural diagram of an embodiment of a mineral exploration system provided by the present invention. The arrow direction in FIG1 represents the direction of electrical signal transmission. As shown in FIG1 , the mineral exploration system 1 includes: a microwave transmission module 10, a Rydberg atom antenna 20, and a signal extraction module 30. The microwave transmission module 10 and the signal extraction module 30 are both connected to the Rydberg atom antenna 20.

[0037] The microwave transmitting module 10 is used to transmit detection microwaves into the underground, where the detection microwaves interact with the underground structure to generate reflected microwaves;

[0038] It should be noted that microwaves have strong penetrating power and can penetrate deep into the underground to interact with underground minerals and soil, triggering complex interactions (due to the absorption, scattering and reflection characteristics of microwaves by underground structures). Different types of minerals and soils will show specific responses under the action of microwaves, producing unique reflected microwave response spectra. The reflected microwave frequency usually appears to be lower than the detection microwave frequency. This frequency change can be used to reflect the different characteristics of the underground structure, providing rich information for subsequent exploration and achieving comprehensive perception of the underground structure. At the same time, microwave technology, as a non-invasive detection method, reduces the impact on the surface and provides the possibility for environmentally friendly exploration.

[0039] The Rydberg atomic antenna 20 is used to receive the reflected microwaves and generate a reflected signal based on the reflected microwaves;

[0040] It should be noted that due to the complexity of the underground structure, the frequency of the microwave signal may change many times. At the same time, the microwave signal may be subject to various interferences and attenuation during underground propagation, resulting in signal weakening, which causes the problem of capturing the microwave signal. The present invention introduces the Rydberg atomic antenna 20, a high-energy atomic structure with a strong sensitivity to microwaves, to absorb and sense microwaves within a certain frequency range in the reflected microwaves, thereby effectively improving the sensitivity and capture efficiency of the exploration signal.

[0041] The signal extraction module 30 is used to extract the fingerprint signal of the underground structure from the reflection signal.

[0042] It should be noted that fingerprint signals are signals with specific frequency and intensity. Fingerprint signals have unique identification in underground structures and represent the specific composition and properties of different types of minerals. Through in-depth analysis of fingerprint signals, explorers can accurately identify the key information of mineral types, underground structure composition, distribution and abundance in underground structures, providing an important reference basis for subsequent exploration.

[0043] Compared with the existing technology, the present invention uses a microwave transmitting module 10 to transmit detection microwaves into the underground, and the detection microwaves interact with the underground structure to generate reflected microwaves. A Rydberg atomic antenna 20 is used to receive the reflected microwaves and generate a reflected signal based on the reflected microwaves. A signal extraction module 30 is used to extract the fingerprint signal of the underground structure from the reflected signal to achieve mineral exploration. By combining the non-invasiveness of microwave technology and the high sensitivity of Rydberg atomic antenna 20 technology, more in-depth and accurate information extraction of underground structures is achieved, effectively improving exploration efficiency.

[0044] In some embodiments, the frequency range of the probe microwaves is 300 MHz to 40 GHz.

[0045] It should be noted that the frequency of the detection microwave ranges from 300MHz to 40GHz, covering a variety of minerals, so that the microwave transmission module 10 can provide stable radiation performance within a wide range of frequencies, adapting to the frequency characteristics of different types of minerals in underground structures and different frequency detection requirements.

[0046] In some embodiments, the signal extraction module 30 is used to perform full spectrum analysis on the reflected signal to extract the fingerprint signal of the underground structure.

[0047] It should be noted that through the spectrum analysis algorithm, the full spectrum signal can be analyzed efficiently and quickly, including multi-dimensional information such as frequency and amplitude, to capture weak but important signal components, not just limited to a specific frequency range, and then use the feature extraction algorithm to accurately extract the fingerprint signal of the underground structure from the full spectrum signal.

[0048] In some embodiments, the fingerprint signal includes a chemical composition fingerprint, a structural feature fingerprint, a water content fingerprint, an ore salinity fingerprint, and a frequency and intensity combination fingerprint.

[0049] It should be noted that the chemical composition fingerprint includes information on the chemical composition of the underground structure, such as metals, minerals, compounds, etc. The structural characteristic fingerprint includes structural characteristics such as density, porosity, and structure of the underground structure, and information on stratum composition and arrangement. The water content fingerprint includes information on the water content in the underground structure, which helps to identify aquifers or water-containing minerals. The ore mineralization fingerprint includes specific signals of mineralization, called the fingerprint of the ore type. The frequency and intensity combination fingerprint includes the specific combinations of microwave frequencies and intensities exhibited by different types of minerals.

[0050] In order to prevent data distortion that may be introduced during signal transmission and processing, in some embodiments, referring to FIG1 , the system further includes a signal processing module 40 , and the Rydberg atom antenna 20 and the signal extraction module 30 are both connected to the signal processing module 40 ;

[0051] The signal processing module 40 is used to amplify and filter the reflected signal to obtain a processed signal;

[0052] The signal extraction module 30 is used to extract the fingerprint signal of the underground structure from the processed signal.

[0053] It should be noted that the reflected signal is accurately amplified by the signal processing module 40 to strengthen the weak signal so that it can be presented more clearly in the subsequent analysis. The amplified signal is then finely filtered by a bandpass filter to remove irrelevant signals and noise, ensuring that only valid information related to the underground structure is retained in the subsequent analysis process.

[0054] In order to adapt to the changes in the complex underground environment and ensure that the detection microwaves effectively penetrate the surface and have sufficient energy to penetrate into the underground, in some embodiments, referring to FIG. 1 , the system further includes a detection feedback module 50 connected to the microwave transmission module 10 ;

[0055] The detection feedback module 50 is used to obtain first parameter data of the reflected microwave in real time and generate a first control signal based on the first parameter data;

[0056] The microwave transmitting module 10 is used to adjust the second parameter of the detection microwave in response to the first control signal.

[0057] Further, in some embodiments, the first parameter includes at least one of frequency and intensity.

[0058] It should be noted that the changes in the frequency and intensity of the reflected microwaves can reflect the characteristics of different types of soil and minerals underground, and they are indicators of the interaction between the underground structure and the detection microwaves. In this embodiment, the detection feedback module 50 also obtains the second parameter data of the detection microwaves. The detection feedback module 50 obtains the first parameter data and the second parameter data through the sensor network, and generates a first control signal based on the first parameter data and the second parameter data. The sensor network includes sensors arranged underground and sensors on the microwave transmission module 10. The sensors arranged underground are responsible for monitoring the frequency and intensity of the reflected microwaves, recording the interactive response of the microwaves and the underground structure in real time, and providing real-time data streams.

[0059] Further, in some embodiments, the second parameter includes at least one of direction, frequency, and power.

[0060] It should be noted that by adjusting the frequency and power of the detection microwaves, it is ensured that the detection microwaves can effectively penetrate the surface and have sufficient energy to penetrate into the underground. By adjusting the direction of the detection microwaves, the detection microwaves can penetrate the surface more accurately and improve the penetration depth of the microwaves. Among them, the microwave transmitting module 10 adjusts the direction of the detection microwaves according to the phased array antenna technology. The phased array antenna technology realizes precise control of the beam by controlling the phase difference, so that the microwaves can penetrate the surface in a more precise direction.

[0061] In order to ensure that the target microwave signal can still be effectively captured in a complex underground environment, in some embodiments, the system monitors changes in the working state in real time and dynamically adjusts the parameters of signal amplification and signal filtering. Specifically, referring to FIG. 1 , the detection feedback module 50 is further connected to the signal processing module 40;

[0062] The detection feedback module 50 is further configured to obtain sensing state data of the Rydberg atom antenna 20 and generate a second control signal based on the first parameter data and the sensing state data;

[0063] The signal processing module 40 is further configured to adjust a third parameter of the signal processing module 40 in response to the second control signal.

[0064] Further, in some embodiments, the third parameter includes a magnification factor.

[0065] It should be noted that dynamically adjusting the signal amplification factor according to the actual state of the system can adapt to changes in microwave signal intensity at different depths and geological conditions. In this embodiment, the third parameter also includes the characteristic parameters of the bandpass filter. Only signals within a specific frequency range are passed through the bandpass filter, and noise and interference signals of non-target frequencies are removed. The characteristics of the filter are adjusted according to the real-time monitored underground structure response to improve the adaptability of the system.

[0066] In order to improve the recognition accuracy of the fingerprint signal, in some embodiments, as shown in FIG1 , the system further includes a database module 60 connected to the signal extraction module 30 ;

[0067] The database module 60 stores various mineral information;

[0068] The signal extraction module 30 is further used to compare the fingerprint signal with the mineral information to obtain the accuracy of the fingerprint signal.

[0069] It should be noted that mineral information includes parameters such as rate and intensity. The frequency and intensity of the fingerprint signal are compared with the mineral information in the database to identify the type and distribution of underground minerals. Data association analysis technology is introduced to associate signals of different frequencies and intensities to improve the comprehensiveness and accuracy of mineral information.

[0070] In addition, the present invention also establishes a high-speed data transmission channel to ensure that a large amount of data collected in real time can be quickly transmitted to the data processing center, including optical fiber networks or other high-speed communication technologies, and designs a large-capacity data storage system to store the data collected in real time, and adopts an efficient data compression algorithm to minimize the storage space occupied.

[0071] In order to better implement a mineral exploration system 1 in an embodiment of the present invention, based on the mineral exploration system 1, correspondingly, as shown in FIG2 , an embodiment of the present invention further provides a mineral exploration method, including:

[0072] S201, transmitting a detection microwave into the underground, where the detection microwave interacts with the underground structure to generate a reflected microwave;

[0073] S202, receiving reflected microwaves based on a Rydberg atom antenna, and generating a reflected signal based on the reflected microwaves;

[0074] S203: Extracting a fingerprint signal of the underground structure from the reflected signal.
