Chinese researchers have successfully tested the world’s first submarine detection devices based on terartz technology, according to SCMP News. The mechanism is capable of detecting small surface fluctuations emanating from low-frequency sources in the open sea, with a height of only 10 nanometers during testing. This surpasses the capabilities of existing devices at this level.
The tracking and analysis of waves not only enables the detection of underwater ships but also facilitates the collection of valuable intelligence, such as the acoustic profile or model of a ship. The research conducted by scientists from the National University of Defense Technology of the PRC was published on August 11 in the scientific journal “Journal of Radars.”
The terartz technology operates within the range between microwave and infrared radiation and is considered a potential solution for future communication systems, including 6G. Electromagnetic signals in this range carry a larger amount of information and can also collect data about the environment. Terartz scanners are already being used in some Chinese airports to detect prohibited objects underneath passengers’ clothing.
Previously, generating terartz signals was a challenging task. However, recent investments in 6G device development have led to a breakthrough, making the technology more widely accessible. The modernized sensor can be installed on various platforms, with small drones being the most optimal option due to their mobility, low cost, and flexibility, according to experts cited in the researchers’ work.
In addition to submarines, the system can supplement existing submarine detection methods such as magnetometric detectors, radar, and laser complexes. The mechanism can also be used for communication between underwater ships and allied planes or vessels during military operations. The commander can encode messages in surface fluctuations too small for enemy detection.
Scientists have already conducted separate experiments testing the close connection between the aquatic environment and the air, demonstrating successful results for 6G communication, the researchers noted.
