| Like bats, dolphins use echolocation, an internal sonar system, to help them navigate, avoid predators and find food. |
| With radar, sonar, fish-finders and echograms she could pinpoint and capture whole schools of fish with chilling effectiveness. |
| The system also has three flank arrays on both the port and starboard sides and an intercept sonar. |
| Whilst sound carries better in water than in air, that hasn't stopped mammals from using sonar in the air too. |
| Lidar is a remote sensing technique that uses laser light in much the same way that sonar uses sound or radar uses radio waves. |
| But Balcomb said he is fighting, nonetheless, to prove that sonar is dangerous to orcas too. |
