Dolphin radar could help detect bombs


British engineers have taken inspiration from dolphins for a new type of radar that could help detect roadside bombs more easily. The device sends out two pulses instead of one, mimicking how dolphins pinpoint their prey. The twin inverted pulse radar (TWIPR) can distinguish between the electronics at the heart of an explosive and other “clutter” such as pipes or nails. Experts said the system “showed promise”.

The radar device has been developed by a team led by Prof Tim Leighton, of the University of Southampton, and scientists from University College, London.

Prof Leighton took his inspiration from the way dolphins are able to process their sonar signals to pinpoint prey in bubbly water.

Some dolphins blow bubble nets around schools of fish to force them to cluster toge...
