Scientists have created microwave technology to look through walls and find objects at hypersonic speed
A scientific group working at the US National Institute of Standards and Technology (NIST) has successfully created a unique electronic system that capable of real-time image acquisition of objects located behind walls, as well as register objects moving with hypersonic speed.
New microwave technology
Of course, you and I cannot look through walls, but this is because the human eye perceives types of wavelengths that do not penetrate objects very well. However, if we switch to longer wavelengths, say in the microwave mode, then we will be able to “see” objects located behind the walls.
How it all works
If we look at the classic radar system, we will see that in it the sending of a radio wave is performed at the expense of the transmitter. The sent waves are reflected from an object within the range of the transmitter and are recorded by the receiver.
So, by analyzing the data of this radar "echo", the location, size and movement of objects in this area are determined. And this method often uses multiple receivers and fewer transmitters.
The system, developed at NIST, works as follows: microwaves are sent through several transmitters, and all reflections are collected by one powerful and very sensitive sensor.
In addition, the system also detects waves that are reflected from other objects returning to the receiver. And this will allow you to quickly and accurately find out and tell you what is in a particular place.
Thus, the system makes it possible to see through solid objects and form an accurate picture of what is actually located behind them. In addition, for such a system it is not difficult to detect objects through adverse weather events (rain, fog, etc.).
The system is also capable of fixing and tracking objects that move at hypersonic speed, for example, planes, rockets and various space debris.
Scientists shared the results of their work and some of their findings in the pages of the journal Nature Communications.
In the meantime, the technology is in its infancy and it is not known when it will find widespread use.
