Radar uses electromagnetic waves through the air to detect objects when the wave hits them and bounces back. These waves' quality degrades greatly when it passes through a liquid or a solid and would bounce back immediately. Sending a radar signal through water would be nearly impossible as it would partially bounce back the second it hit the water itself.
Sonar is what is used to detect objects underwater, as it uses sound waves instead, which work more strongly on vibrations made by a sound signal/wave.
Radar uses electromagnetic waves through the air. These waves would degrade WAY too much traveling through the denseness of large volumes of water. This is why SOUND waves are used underwater instead, in a technique known as sonar.
What else can I help you with?
Was there been a pyramid found under water?
no there has not been a pyramid found under water
Is the north pole under water?
no, but it is on top of the water
Which planet has a moon with a possible ocean water under a crust of ice?
Jupiter's moons - Europa and Ganymede possibly have oceans of liquid water under their crust. Saturn's moon - Enceladus also has a possible ocean of water under it's crust.
Is Atlantis under water?
yes its believed to be under the island Malta in the medderterainian sea
Is the tyne tunnel built under water?
The Tyne River Tunnel is indeed built partly under water. The lowest spot in the tunnel is 85 feet below the high water mark of the river.
What are the differences between radar and sonar in terms of their applications and capabilities?
Radar and sonar are both used for detecting objects, but they operate in different mediums. Radar uses radio waves to detect objects in the air or on the ground, while sonar uses sound waves to detect objects underwater. Radar is better for long-range detection and tracking of objects in the air, while sonar is better for underwater navigation and detecting objects beneath the surface of the water.
What is the radar for?
Radar is used to detect concentrations of water droplets in the atmosphere, which tells meteorologists where rainfall, snow and hail are occurring.
How is radar similar to active sonar?
Radar and active sonar both emit energy pulses and measure the time it takes for the signals to bounce back after hitting an object. They both use the principle of echolocation to detect and locate objects in their respective mediums of air and water.
Why do submarines hide if they are detected by radar systems?
Submarines will retreat to the depths if they are detected by radar. Note that radar can only detect a submarine if they are on the surface or if they have a mast or periscope sticking up out of the water. Radar has a terrible time trying to penetrate water, so if a submarine is detected because something is sticking up out of the water, the submarine will submerge to get some depth. Radar can't detect it down there. Also, the submarine will be trying to get out of the area and become "lost" in the ocean where it cannot be detected or located.
Why can fish detect sound under water?
They have (inner) ears.
A fishing boat using sonar to locate fish is employing what?
A fishing boat using sonar to locate fish is employing reflection. The technique that uses sound propagation to detect objects under the water.
What did the military use sonar's for?
Sonars were used to detect any objects that got into the detection field of the sonar. By this, the military could detect enemy submarines etc., which they couldn't see normally because of the opacity and/or darkness of the water.
How far can sonar detect?
The distance that sonar can detect objects underwater varies depending on factors like the power of the sonar system, water conditions, and the size of the object being detected. In general, sonar can detect objects up to several miles away when using higher power systems in optimal conditions.
What tool detects water leaks underground?
Ground penetrating radar (GPR) is commonly used to detect water leaks underground. GPR works by sending radar pulses into the ground and measuring the reflections to identify anomalies like water leaks. This non-invasive method is effective in locating leaks without the need for excavation.
What boats use to locate objects under water?
Sonar
What is the instrument used in seeing objects at the surface of the water from a submarine under water?
Periscope
Can ir sensor pass through water?
No, IR sensors typically cannot pass through water as water absorbs and scatters IR light, interfering with the sensor's ability to detect objects. This reduces the sensor's effectiveness and accuracy in detecting objects through water.
