Sonar Applications

− Uses sound waves to measure or detect objects on or under

the surface of the water.

− Similar to medical ultrasound, beamforming is used and an

array of receivers produces spatial differentiation.

− Unlike medical ultrasound, lower frequency's and higher gain

ranges are sometimes needed to measure very far distances.

− Typical Sonar applications include:

• Fish finders – lower channel count, smaller size

• Deep water survey – longest distances

• Military and Stealth applications
