China released the first full-array three-dimensional ground penetrating radar

With the urbanization process, underground space security issues have become increasingly prominent, and more and more pipelines and pavements have been aging. Urban underground space is like an invisible "dark net", which has hidden dangers such as road collapse and gas pipeline leakage. From July to the end of this year, there were more than 160 underground pipeline accidents and more than 60 road collapse accidents in China. Many accidents caused casualties and property losses.

"Eagle Eye-A (Array)" relies on military-to-civilian technology to quickly and comprehensively and accurately "see through" urban underground multi-material municipal pipelines, oil and gas pipeline information, as well as urban roads, loose, water-rich and other soil disease information. . It can realize the acquisition and storage of three-dimensional data within 6 meters underground, the detection interval of centimeter level and the measurement of millimeter earth coordinates.

The person in charge of the project introduced that "Eagle Eye-A" truly realized array detection, which adopts multiple transmission and multi-receiving work system, multiple transmitters sequentially transmit ultra-wideband electromagnetic pulses, multiple receivers receive synchronously, combined with array signal processing technology. . Compared with traditional products that can only form measuring lines in the direction of motion, the product can simultaneously form multiple lines parallel and perpendicular to the direction of motion during radar motion, realizing real-time acquisition of underground three-dimensional information.

Even in the most demanding underground space survey, the Hawkeye-A can reduce the time required for detection by 80% compared to the conventional manually operated single-channel radar; compared to the non-array probe for vehicle towing Ground-based radar, detection time can be reduced by 50%.

At the same time, there are few studies on artificial intelligence technology in the field of automatic classification and identification of geological structures in China. As a research institute for artificial intelligence technology research in the military industry, Aerospace 35 has taken the lead in realizing the application of artificial intelligence technology in the field of geological exploration with its professional advantages, and has made breakthroughs in intelligent detection of underground pipelines.

The "Eagle Eye-A" loaded artificial intelligence processing system can independently detect, identify and mark multiple types of underground anomaly information, complete the interpretation of information such as underground pipelines and road soil diseases, and immediately generate general results "messages". Greatly reduce the workload of manual data analysis and improve the efficiency and accuracy of data interpretation.
