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.

TWIPS exploits the natural abilities of dolphins to process their sonar signals to distinguish between targets and clutter in bubbly water. Some dolphins have been observed to blow 'bubble nets' around schools of fish, which force the fish to cluster together, and their sonar would not work if they could not distinguish the fish from the bubbles.
