The two types of sonar are active and passive.
Active sonar uses a transmitter, a device that converts electrical energy to sound energy, to send out sound waves. The sound waves travel through the water until they strike an object. The object reflects them in various directions. Some of the reflected waves return to the sonar, where they strike a receiver. Sonar determines distances by measuring the time taken for a sound wave to travel from the transmitter, reflect from the object, and travel to the receiver.
Passive sonar receives sound waves given off by some other source, but does not transmit sounds. Passive sonar can therefore determine the direction of an object, but is not as effective as active sonar in determining its distance.

How many different sonar systems are there?
There are various sonar systems available, each with unique features and applications. Some common types include single-beam, multi-beam, side-scan, and synthetic aperture sonar systems. These systems are tailored for specific purposes such as navigation, bathymetry, underwater mapping, and object detection.
What Types of waves are used in echolocation?
Sound waves are typically used in echolocation. Animals emit high-frequency sound waves that bounce off objects in their environment and return to them as echoes, allowing them to determine the location, size, and shape of objects. Bats, dolphins, and some species of birds are known to use echolocation.
What two pieces of information are needed to map the ocean depth using sonar?
To map ocean depth using sonar, two key pieces of information needed are the time it takes for the sound waves to travel from the sonar device to the seafloor and back (ping time), and the speed of sound in water at different depths. By calculating the distance based on ping time and speed of sound, the ocean depth can be accurately mapped.
Bearing resolution of a sonar?
Bearing resolution in sonar refers to the ability to distinguish between two closely spaced objects in terms of their direction relative to the sonar transducer. It depends on factors like the beamwidth, signal processing techniques, and the frequency of the sonar system. Higher bearing resolution allows for better target discrimination and localization.
How are sonar and radar different?
Sonar uses sound waves to detect objects underwater, while radar uses radio waves to detect objects in the air or on the ground. Sonar is typically used in marine environments, while radar is commonly used in aviation and meteorology.
What are the different type of sonar?
The two different types of sonar are passive and active.
What is sonar and how does it detect aeroplanes?
Sonar is the generic name of the technology that is used to locate objects underwater. Sonar systems are of two basic types - active and passive. In active sonar the system let's out a pulse of sound and then the operator listens for echoes. The passive sonar the operator listens to sounds emitted by the object one is trying to locate.
Which is correct grammar Two Different types or Two types?
Two types. By saying there are two 'types' you are already stating that there are 2 differentthings and so the word 'different' isn't necessary.
