New radar system inspired by dolphins to detect hidden surveillance and explosive devices

Inspired by the way dolphins hunt using bubble nets, scientists have developed a new kind of radar that can detect hidden surveillance equipment and explosives. The twin inverted pulse radar (TWIPR) is able to distinguish true 'targets', such as certain types of electronic circuits that may be used in explosive or espionage devices, from 'clutter' (other metallic items like pipes, drinks cans, nails for example) that may be mistaken for a genuine target by traditional radar and metal detectors.
