We now know that rising sea temperatures will affect sonar performance, sometimes greatly affecting submarines’ ability to find ships and other submarines, and ships’ ability to find them. This leaves ...

Sonar sent sound waves to the ocean floor and measured how long it took for the waves to bounce back, giving scientists their ...

most often sound waves. While a well-known use of this is sonar, ultrasonic sensors can also be put to use to make a radar-like system. This ultrasonic radar project is from [mircemk] who uses a ...

To make the detection more sensitive, researchers built the phased-array sonar system. This consists of multiple units that can transmit sound waves and those of different frequencies ...

So, instead of using ultrasound, radio waves are used as they travel at 300,000,000 m/s. It works in the same way as sonar but with radio waves in place of ultrasound. A short pulse of radio waves ...

Advances in technology are helping explorers fulfill their purpose: Mapping the ocean floor in tiny detail for the first time.

Waves crash, tides go in and out ... At the heart of the “surfsonar” is the Ping Sonar Echosounder, a sonar transducer designed for AUV’s and ROV’s. [foobarbecue] embedded the transducer ...
