Summary of the Article:
Sound Navigation and Ranging (SONAR) is a technique used for navigation and object detection using sound propagation. It is used by the Navy to detect submarines and mines in the ocean. Sonar is also utilized for military purposes, such as mine detection, depth information, and anti-submarine warfare. There are two types of sonar: active and passive. Sonar can be divided into three main categories: Searchlight Sonar, Sector Scan Sonar, and Scanning Sonar. The main difference between sonar and radar is that sonar uses sound waves, while radar uses electromagnetic waves. Sonar is called so because sound waves travel farther in water compared to radar and light waves. The detection range of sonar can vary but can reach up to 2400m.
Key Points:
- The full form of SONAR: Sound Navigation and Ranging.

The full form of SONAR is Sound Navigation and Ranging.
The full form of RADAR is Radio Detection and Ranging.
Navy sailors use sonar to detect submerged objects such as submarines and mines. The ocean is filled with natural and man-made sounds, and sonar helps in distinguishing them.
Sonar equipment is used by submarines, warships, and other naval platforms for safe navigation, mine detection, depth information, and anti-submarine warfare.
There are two types of sonar: active and passive. Active sonar emits sound waves and analyzes the reflected signals, while passive sonar listens for sounds emitted by other sources.
Sonar is divided into three main categories based on the type of scanning technique used: Searchlight Sonar (PPI Sonar), Sector Scan Sonar, and Scanning Sonar.
Sonar uses sound waves to detect objects underwater, while radar uses electromagnetic waves (radio or micro waves) to detect objects in the air or on the surface. Sonar operates in water, while radar operates in the air or on land.
Sonar is called so because sound waves can travel farther in water compared to radar or light waves. This makes it useful for exploring and mapping the ocean.
The detection range of sonar can vary but can reach up to 2400m (divided into 15 steps). There are two types of sonar: Single Frequency Sonar and Dual Frequency Sonar.
Sonar equipment is used for various applications such as providing depth information, mine detection, and anti-submarine warfare.
No, while sonar is commonly associated with military use, it is also used in civilian applications such as underwater exploration and mapping, fisheries, and oceanography.
Active sonar emits sound waves into the water and analyzes the echo or reflected signals. It measures the time taken for the signals to return and calculates the distance and composition of the objects.
The main advantage of sonar over radar is that sound waves travel farther in water, allowing for greater coverage and detection range underwater. Sonar can also provide more detailed information about underwater objects compared to radar.
Yes, sonar can be used in shallow waters, but the depth and composition of the water may affect the accuracy and range of the sonar signals.
While sonar is primarily used in water environments, variations of sonar technology, such as “laser sonar” or LIDAR, can be used in air or land-based environments for object detection and ranging.
What is the full forms of sonar
The full form of SONAR is Sound Navigation and Ranging. It is a technique involving the use of propagation of sound for navigation, and it also can be used for distant object detection and interaction with other objects.
What is radar full form sonar
SONAR stands for Sound Navigation and Ranging, and RADAR stands for Radio Detection and Ranging.
Why do Navy use sonar
Navy Sailors use sonar to detect submerged objects such as submarines and mines. The ocean can be a very noisy place, full of sounds from natural sources like marine animals, breaking waves, rain, lightning, and earthquakes, to man-made sources like ships and seismic exploration.

What is sonar for military
Submarines, warships and other naval platforms use sonar equipment and sonar systems to safely navigate deep waters. Sonar equipment is also used for mine detection, providing depth information and anti-submarine warfare (ASW).
What are the 2 types of sonar
There are two types of sonar—active and passive.
What are the three types of sonar
Sonar is divided into 3 main categories: Searchlight Sonar (PPI Sonar), Sector Scan Sonar, and Scanning Sonar.
What is sonar vs radar
RADAR is a detection and ranging system that uses electromagnetic wave (radio or micro waves) to detect the objects. SONAR is a detection system that uses sound waves to detect the objects. RADAR uses radio wave for its operation. SONAR uses sound wave for its operation.
Why is it called sonar
Sonar, short for Sound Navigation and Ranging, is helpful for exploring and mapping the ocean because sound waves travel farther in the water than do radar and light waves.
How far can sonar detect
The detection range is from 10 to 2400m (divided into 15-steps) and there are two types of Sonar: Single Frequency Sonar and Dual Frequency Sonar.
Does the military still use sonar
Military applications. Modern naval warfare makes extensive use of both passive and active sonar from water-borne vessels, aircraft and fixed installations.
How much does a sonar technician earn in the US Navy
The average salary for a Sonar Technician is $47,512 per year in United States, which is 20% lower than the average US Navy salary of $60,034 per year for this job.
Is sonar still used today
This technology continued to improve and was even more helpful by World War II, and is still used on military vessels today. SONAR technology mostly grew due to naval military use. However, it is very helpful in underwater exploration and is used widely today.
Do ships use sonar or radar
Passive sonar systems are used primarily to detect noise from marine objects (such as submarines or ships) and marine animals like whales.
Do cars use radar or sonar
RADAR is especially good at detecting metal objects, like cars, trucks, and buses. As the image above shows, they are essential for collision warning and mitigation, blind-spot detection, lane change assistance, parking assistance, adaptive cruise control (ACC), and more.

Which country invented sonar
Sonar was first developed – as a practical method of detecting underwater hazards (eg, submarines, icebergs) and for measuring water depths – by Constantin Chilowsky and Paul Langevin in France during WWI, with the collaboration of the Canadian R.W. BOYLE.
How deep can sonar reach underwater
One sonar system is optimized for producing high-resolution maps of the bottom at depths down to 8,000 meters. Another system works best in shallower depths of less than 2,000 meters, such as those found on continental shelves.
Can sonar detect a person
Abstract. Sonar is very useful to locate shipwrecks, human bodies and other objects underwater and assess the context in which they drowned.
How deep can sonar reach
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 long does it take to become a sonar technician
Following Boot Camp, you'll report to a Sonar Technician “A” School in San Diego, CA, for 10 weeks, where you'll learn the fundamentals of sonar technology with basic operator and analyst skills. Once you complete that course, you'll spend an additional 6-8 weeks taking a more in-depth sonar operator course.
Is radar faster than sonar
Radar waves travel through air at the speed of light (~3.0×108 m/s) and sonar waves travel through water at the speed of sound (~1.5×103 m/s).
Can sonar detect speed
S.O.N.A.R, an acronym for “sound navigation and ranging,” is a similar system to radar in terms of transmitting and receiving waves through pulses to determine distance and speed. However, it functions through the use of sound waves and is highly effective underwater.
What was the first sonar called
Interest in Sonar increased during World War I when there was a need to be able to detect submarines. In 1915, Paul Langévin invented the first sonar type device for detecting submarines called an "echolocation to detect submarines" by using the piezoelectric properties of the quartz.
When did the US start using sonar
During the 1930s American engineers developed their own underwater sound-detection technology, and important discoveries were made, such as the existence of thermoclines and their effects on sound waves. Americans began to use the term SONAR for their systems, coined by Frederick Hunt to be the equivalent of RADAR.
