Researchers adopt the dolphin sonar to detect explosives

dolphinsResearchers have discovered a new one radar that could be used to detect IEDs (IED). The discovery was inspired by an unlikely source: dolphins. The same technology could also be used to find buried earthquake victims, lost chipped animals, or tiny monitoring that are hidden in walls.

But how do dolphins come into play? The first writer of the new research, Timothy Leighton of the University of Southampton, told New Scientist that he watched a video showing dolphins blowing bubbles to locate a school of fish, and wondered how dolphins can use this sonar to track fish with all that "noise" " around them. After several tests he found that the dolphin sends "two pulses in quick succession, identical to each other, but reversed". This way he can find his targets from the bubbles. It is unclear whether this method from dolphins, but it works and Leighton decided to apply it to radars.

Researchers call the twin inverted radar pulse technique or in English Twin Inverted Pulse Radar (TWIPR). Όπως ακριβώς με τη μέθοδο σόναρ στέλνει δύο πανομοιότυπα ηλεκτρομαγνητικά κύματα σε ανεστραμμένη φάσεις – δηλαδή, όταν το ένα κορυφώνετε το άλλο γυρίζει. Έτσι είναι σε θέση να προσδιορίσει τους ημιαγωγούς από άλλα αντικείμενα από τον τρόπο που σκορπίζονται τα κύματα, όταν έρχονται σε επαφή. Στη μελέτη που περιγράφει τα ευρήματά τους, οι ερευνητές αναφέρουν ότι μπορούν να διακρίνουν ακόμα και το σκουριασμένο μέταλλο. Μπορούν να ανακαλύπτουν επίσης , με ή χωρίς την SIM, ή ακόμα και χωρίς την μπαταρία.

In accordance with TheVerge the new technology allows for the detection of explosive devices as well as the search for mobile phones, which may allow victims to be found buried after a collapse of a building.
