What is a system that uses multiple sonar devices?
Two or more sonar devices (transducers) could be set up in a sonar array of some sort. Multiple hydrophone setups are not uncommon in several applications.
What was the date sonar was invented?
The first recorded use of sonar was in the time of Da Vinci - 1490. Stick a hydrophone in the water and listen to see what you can hear. That's sonar. It was left until the early 1900's when the Titanic sunk that sonar was looked at to aid marine navigation. The development of submarines at about this time caused the military to investigate it. Electronics was growing up in the same period, and all these factors combined to bring us "modern" sonar. A link to the Wikipedia article is provided, and the "History" portion of the post is short and easy to read. Why not surf on over and check it out?
What two words make up flurry?
flutter and hurry
Why sonar is not used in place of radar?
Sonar is used below water. Radar is used in the air. For Sonar to be used in the air, the sound would be deafening. The noise from an airplane at a low altitude flying faster than the speed of sound broke many windows across the United States. People can go deaf if constantly exposed to sound greater than 120 decibels. To use sonar in place of radar would require several thousand decibels.Another answer:Bats use sonar in air and their chirps are not deafening. Sonar is used on automotive parking and backing sensors. Robotic systems commonly use sonar to measure the range of objects. Some blind people have developed the technique and teach it to others--clicking or hissing to navigate in unfamiliar surroundings (it's really not hard). Doppler sonar is used in meteorology, particularly around airports, to measure windspeed, direction and turbulence aloft. Sonar is not used in place of radar because its useful range is limited--not because it would be deafening. The highest power terrestrial sonar devices have a range up to 3 km, but only emit about 40 dBA.
What Types of waves are used in echolocation?
As the name suggests, sonar uses sonic waves (sound). Typically, sonars use sounds with frequencies inaudible to human ear.Another answer:Actually, sonar uses a wide range of frequencies. Very low frequencies (100 Hz to 1 kHz) are used for long range detection and deep sea floor sounding. Midrange frequences (1 kHz to 10 kHz) are used for target identification. Ultrasonic frequencies (50 kHz and up) are used in navigation and commercial sonar devices like fish finders.

What are some negative effects of sonar?
Some negative effects of sonar are that marine animals like whales and dolphins are being effected and not being able to use their sonar very well. It is proven that the reason whales "beach" is because the tests of low-frequency sonar's mess up the hearing of whales and make them lose their sense of direction.
How accurate is the expression 'blind as a bat'?
If it relates to person, not very, as bats do have sight although poor and people have no sonar facility to make up it.

What term is used to the number of people that make up a nation?

Can a sonar machine identify the object showing up on the sonar?
Sonar (which stands for SOund NAvigation and Ranging) can be made to identify the object it pings on - if active sonar; if passive sonar, identify the object making the sound it picks up. The higher the frequency of the active sonar ping, the better the resolution - but the shorter the range. At higher resolutions, it is not hard for the sonar to identify the object it pings on. At lower frequencies, the range is greater but it is harder for the sonar to identify what is being pinged. Another benefit of active sonar is the range and direction of the target can be discerned. Passive sonar just listens to the ambient water. Identification of the sound source can be made if the frequencies of the target making the sound are known and identified in a database. One problem with passive sonar is that it is hard to know the range of the target making the sound, although the direction will be known. Water temperature and depth have a great effect on sonar, so this must be taken into account when calculating distance. Sonar is used in the Military, Geological Surveying, and the Medical field.
Does a ship have a sonar?
Most modern combat Navy surface vessels have Anti-Submarine Warfare (ASW) sonar arrays of some type, and at least 1 Aircraft Carrier does as well (newer carriers use their escort vessels for ASW sonar screens). Essentially, that comes down to Cruisers, Destroyers, and Frigates, which make up the bulk of a Carrier Battle Group or Task Force screen to protect the Carrier from submarine threats. However, those ships, as well as Carriers, also use fixed and rotary wing aircraft with deployable (dipping) and expendable (sonobuoys) sonar as well. Ship sonar systems include the main forward sonar arrays, as well as deployable Variable Depth Sonar (VDS) towed sonar systems.
How many words can you make out of mend?
you can make up end, men, Ned, den. you can make up four words
What do bats use to make up for their blindness?
They have a form of sonar. They send out a signal and it bounces back giving them information about what is ahead of them and around them. Dolphins do the same thing.
What to words make up the word who'll?
The two words 'who' and 'will' make up the contracted word 'who'll'.
