Sonar

Discover how sonar technology can unlock the mysteries of the deep sea. Dive into the world of sonar and explore its fascinating applications in marine exploration and navigation.
A flying bat generates ultrasound to find the distance and density of the obstructing object and pilots itself accordingly. SONAR (Sound Navigation and Ranging) is based on the same unique technique of sound propagation to detect or locate objects that are out of our reach or obscured. It was first used by Leonardo da Vinci when he submerged a tube underwater and listened through the opening on above to determine the location of other vessels. This blog explores the major applications of Sonar. Sonar, Medical Science, Submerged, Ultrasound, Propagation, Equations, Pilots, Vessel, Underwater

Students use ultrasonic sensors and LEGO© MINDSTORMS© EV3 robots to emulate how bats use echolocation to detect obstacles. They measure the robot's reaction times as it senses objects at two distances and with different sensor threshold values, and again after making adjustments to optimize its effectiveness. Like engineers, they gather and graph data to analyze a given design (from the tutorial) and make modifications to the sensor placement and/or threshold values in order to improve the…

MIT Media Lab researchers have designed a system that allows underwater and airborne sensors to directly share data. An underwater transmitter directs a sonar signal to the water’s surface, causing tiny vibrations that correspond to the 1s and 0s transmitted.

MIT Media Lab researchers developed a water-air communication system, Translational Acoustic-RF Communication (TARF), where an underwater transmitter directs a sonar signal to the water’s surface, causing tiny vibrations that correspond to transmitted data, which an airborne highly sensitive radar decodes.
