What is naval sonar?

Sonar (sound navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels.

Is Navy Secf a good job?

“The Sailors in the Submarine Electronics Computer Field (SECF) work with a submarine’s sonar, weapons, communications and navigation systems. The training is rigorous and the career opportunities are equally impressive.”

What does stg stand for in the Navy?

Sonar Technicians, Surface
Sonar Technicians, Surface (STG) operate surface sonar and other oceanographic systems; collect, analyze, and interpret sonar and oceanographic data; operate surface ship underwater fire control systems (with associated equipment) for the solution of Anti-Submarine Warfare (ASW) problems; conduct ordnance evolutions; …

Does the Navy use active or passive sonar?

To detect and counter hostile submarines, the Navy uses both passive and active sonar. Sonar proficiency is a complex and perishable skill that requires regular, hands-on training in realistic and diverse conditions, such as those provided in the AFTT Study Area.

Why is radar not used underwater?

Unfortunately, Microwaves are strongly absorbed by sea water within feet of their transmission. This renders radar unusable underwater. The reason is mainly because radar has a harder time penetrating large volumes of water. … Also, radar is only an active system allowing for your detection by passive sensors.

Does sonar hurt marine life?

Unfortunately for many whales, dolphins and other marine life, the use of underwater sonar (short for sound navigation and ranging) can lead to injury and even death. … These sound waves can travel for hundreds of miles under water, and can retain an intensity of 140 decibels as far as 300 miles from their source.

How does Navy sonar affect whales?

There was anecdotal evidence from whalers (see section above) that sonar could panic whales and cause them to surface more frequently making them vulnerable to harpooning. It has also been theorized that military sonar may induce whales to panic and surface too rapidly leading to a form of decompression sickness.

Do destroyers have sonar?

Destroyer escorts mounted the latest and most up-to-date anti-submarine weapons and detection gear available during World War II, including depth charges, hedgehogs, air and surface search radar, sonar, and a high frequency radio direction finder known as HF/DF.

Can Navy sonar damage whales?

They use it to hunt for mines, but the sound can seriously injure whales. … But active sonar, which bounces high-intensity sound off an object, is more accurate. The Navy’s own studies have shown the impact active sonar has on marine mammals. Even large blue whales will turn away from ships using it.

What are the disadvantages of sonar?

Drawbacks or disadvantages of SONAR

➨SONAR system generates lot of noise which depend on sound levels generated by SONAR. ➨The acoustic waves used in SONAR are affected by sound velocity variations over depth. This causes refraction of acoustic energy. Moreover ocean acts as lossy medium for acoustic waves.

Is Navy sonar killing whales and dolphins?

Explosions, sonar and ship strikes during Navy exercises could harm blue whales 9,248 times over the next five years and the short-beaked common dolphin 6.8 million times under the incidental take permit issued by the National Marine Fisheries Service.

Can a sperm whale make you deaf?

Quite simply, sperm whales are the loudest animals on the planet. … A sound of 180dB is enough to cause drastic cell death in your ears, but the most powerful sperm whale clicks will not merely deafen you: they can vibrate the fragile human body to pieces.

What are two benefits of sonar?

Advantages of Sonar

The advantages of Sound Operated Navigation and Ranging are: Attenuation of sound waves is less in water. Implementation of the system is not expensive. Reliable and Accuracy is high.

What are three uses for sonar?

Nonmilitary uses of sonar include fish finding, depth sounding, mapping of the sea bottom, Doppler navigation, and acoustic locating for divers. A major step in the development of sonar systems was the invention of the acoustic transducer and the design of efficient acoustic projectors.

What’s the difference between active and passive sonar?

What is the difference between active and passive sonar testing? A simplified explanation is that active sonar testing works like an echo repeater, i.e. it will return an echo for received sonar pulses in the water, while passive sonar testing simply emits sound or noise in the water.
