Two types of sonar arrays are gathered together in a single solution known as the Integrated Undersea Warfare system. High-frequency sonar is able to detect underwater minefields, while medium-frequency sonar sniffs outsubmarinesandtorpedoes. The dual-band sonar array is located in the bow of the...
However, high-frequency waves don't spread as much as low-frequency waves. Also, waves with long wavelengths generally travel farther than ones with short wavelengths. There are plenty of other things to learn about sound, but this is what you need to know to understand LRAD systems. We'll...
