Sound wave radar equipment

British scientists have created a dolphin-inspired ultrasound that can detect people trapped underground or buried in snow.

According to AFP, radar devices, like dolphins, can emit two consecutive fast pulses that allow the target to be searched for semiconductor devices and eliminate ambient noise.

"With more precision and speed than conventional radar equipment, new radar detectors can detect roadside bombs, recorders or telephones even in areas where there is a metal jam." , Says Timothy Leighton of Southampton University of Technology.

Inspired by the dolphin's ability to feed on dolphins, the dolphins emit sound and report on the movement of their prey. The team has created a radar-like radar system similar to The way dolphins do to detect semiconductor devices.

The team has also developed a small-sized transmitter with a weight of less than 2 grams and a cheap price that can be hidden in helmets by miners or rescue workers or even in shoes. of the skiers to promote the search feature when the bad situation occurs.

If there are victims trapped in collapsed buildings or miners working underground, the device will pinpoint their exact location and identity with the ability to adjust to human identity. of equipment.

Even with a non-radar detector, the device can also be used to track down cell phones, whether they are turned off, out of battery, or lost.
