STG is the rate, or job, of that person. In this case, it is a Sonar Technician - Surface. They work on the sonar suite of a surface vessel (ie, a ship). The "C" gives that person's rank, which in this case is a Chief Petty Officer. If it was a Senior Chief Sonar Tech, they would be STGCS. If it were a 3rd Class Petty Officer, they would be STG3. The Sonar Tech rating is actually divided between surface and submarine technicians. STS stand for "Sonar Technician, Submarines", where STG stands for "Sonar Technician, Guns", indicating a surface rate.
NO. We call that radar.
The scientist who is credited with inventing sonar is Paul Langevin, a French physicist. In 1915, Langevin developed the first practical application of sonar as a way to detect submarines during World War I. His work laid the foundation for the use of sonar technology in various fields, including marine navigation and underwater exploration.
Yes they do
A sonar transmits sound waves and captures it back after they strike an object. They work on the dopplers principle.
they both work in the night
I don't think the Cinematographer and camera operator's work will be same.the work of Cinematographer is really very difficult to compare camera operator..!
Submariners.
She did her work under the sea in a submarine
The driver/operator makes the vehicle work.
Sonar works by emitting sound waves from a transducer into the water. These sound waves travel through the water until they encounter an object, at which point they bounce back to the sonar device. By measuring the time it takes for the sound waves to return, the sonar device can calculate the distance to the object.
