During the recent one Conflict between Israel and Iran There was a lot of talked about the powerful Israeli antimile defense system, known as the ‘Iron dome’. Europe too wants to build yours and United States shuffled the creation of a ‘golden dome’ that would use a satellite network and would be able to Stop hypersonic missiles. And what about China? Although they have Several antimile systems At different levels, they do not have a “total” shield like the one who wants to build the United States. What they do is a technology that, if applied, would far exceed the detection of missiles from other countries.
A beetle. This kind of beetles receives that name for its ability to detect fire up to 80 kilometers away Thanks to an organ in its most sensitive exoskeleton than most infrared sensors in the market. This has been the inspiration of these Chinese researchers for their new creation: a system that mimics this same sensitivity and allows you to detect hot objects quickly and precisely.
The system. During the investigation, Posted in Nature magazinethe scientists carried out several tests to verify the effectiveness of the system. In the first they built an ‘heteroestructure’ with divel -divelur, a material that offers a high absorption of the middle infrared range, and pentacene, an organic semiconductor. The device could detect radiation to an intensity of only 0.5 millivats per square centimeter, a sensitivity close to that of the beetle. In the second test they used black phosphorus and Indian seleniuro, achieving a photonic memory of 0.5 microseconds, 20,000 times faster than conventional optical storage.
Capacities. Researchers affirm that this technology is able to “detect and identify objects in difficult environments, since it can penetrate obstacles such as smoke, fog and dust, providing clear images and precise detection of objectives.” In addition, it works at room temperature without refrigeration. This technology could be used in various scenarios: fire detection, autonomous driving, night vision systems and of course military environments.
Antimisiles. As we said, China does not have an “dome” antimile system, but this technology could open the door to the creation of one that, According to South China Morning Postit would be much more precise than the ‘Golden Dome’ that Donald Trump wants to build. The key point is that the system integrates detection, memory and processing functions. Current antimisile systems are based on traditional silicon semiconductors and hardware separation (sensors and processors) prevents them from reaching those response speeds.
Nothing concrete. Donald Trump’s ‘golden dome’ is, for now, a proposal that has not yet materialized, just like this hypothetical Chinese dome. What we do know is that China did not make any grace The announcement of this project because “it would raise the risk of converting space into a war zone and creating a career for creating space weapons.” Currently, China has several antimile defense layers: Dong Neng-3an exoatmospheric missile interception system, HQ-19 for medium-range interception and HQ-29 with antisatelite capabilities.
