China developed the world's most sensitive submarine detector?

Chinese scientists have found a new breakthrough in magnetic field detection technology. As a result, they were able to create detectors with unprecedented precision in finding underground minerals as well as ocean submarines.

According to South China Morning Post, the Chinese Academy of Sciences has just released an article saying that scientists in Shanghai are developing a "superconducting superconducting magnetic field probe" and have overcome it. Inspection round of a team of experts.

This technology can be used to detect ground minerals and submarines hidden deep in the ocean.

This probe can be used to identify minerals deep in the ground in Inner Mongolia (China) with extremely high accuracy. In addition, it can also be used to create detectors mounted on a variety of civil and military aircraft as "a high-performance device and an effective engineering solution for mapping resources." nature, archeology and defense ".

"The Chinese military will soon use this technology," said Zhang Zhi, an expert from the China Geological University. "This technology can be used to detect minerals in the ground and the submarine hidden deep in the ocean ".

In fact, anti-submarine aircraft equipped with "extraordinary magnetic detectors" (MAD) have been around since the Second World War. Basically, detectors will monitor the small effects of metal objects cause the Earth's magnetic field, then analyze the data and use complex algorithms to find the location of the target.

However, it will be difficult to find the exact location because the magnetic field signal will decrease very quickly when the target moves away from the detector position. In addition, the aircraft will have to fly low and only detect the position of the submarine that is near the water surface so it will be dangerous. Besides, the strength of the magnetic field signal is also affected by many other factors, such as the material of the submarine shell.

According to Dr. Lei Chong, a research assistant at Shanghai Jiaotong University, the detector uses "superconducting superconducting magnetic probe" , or " MAD superconducting" made by China. The two most fundamental differences compared to other types of detectors from other schools.

First, Chinese detectors were equipped with a large number of transducers. As a result, it can collect more data than traditional detectors, which usually use only one antenna.

Second, Chinese scientists equipped the detector with a superconducting computer chip and cooled with liquid nitrogen. Such a super cool environment can help increase the detector's sensitivity to signals that conventional detectors won't catch.

The prototype of a MAD detector was created by Chinese scientists in 2014.

According to a Chinese Academy of Academy of Science article, superconducting MAD technology has been developed over the past 4 years by a group led by the Shanghai Institute of Information Technology. In addition, China is developing eight different types of magnetic field detectors that are sized and sensitive enough to equip satellites.

The article also adds that most countries in the world, including the US, are experiencing numerous difficulties in developing similar magnetic field detectors. Currently, only Germany is a rare exception beside China.

However, Dr. Lei Chong said that it is still too early to say that China is the world leader in MAD technology as affirmed by the Academy of Academy of Sciences.

"I was really surprised when they made such a announcement. Normally, such information will not be revealed because of their military value ," said Lei Lei , "Military "The US team may have developed the same type of device but kept it quiet. Therefore, it is impossible to compare this country with other countries about this type of sensitive technology only with publicly available information."

"In addition, the transition from a mineral detector to a submarine detector also requires a lot of work. The military sector has different requirements than the civilian sector , " said Dr. Lei. adds.
