Sonar is a system for making a picture of the surrounding environment, using echoes.
Bats use sonar to create a mental picture of the environment. They do this by making high frequency chirps that bounce off any objects within range, and these chirps bounce back off the object to the bat and give it an idea of where it is in the environment. This system of sight has likely been created due to most bats poor eyesight.
Essentially, sonar is a way to see something by using sound. While an echo is a reverberation of a sound within an environment. When you hear an echo, you are hearing a sound made bounce off the surrounding environment and back to your ears.
The system is so useful that is has been developed and employed by the military. The reason for this, is because viewing conditions in certain terrains and locales can be poor, there had to be another way to make a picture of the area they were in. Because sonar uses sound, not light, it is ideal for getting around in areas where normal viewing is impossible.
For example: under the sea, in the air, underground, in snowy environments, or any other area where visibility is very poor.
Sonar location is in the water and echo location is in the air.
basically same but sonar uses ultta sonic waves and echo uses sound in air
Echo sounding is used to get indication of any difference in the properties of the water. Fish finding, and depth sounding would be obvious uses. Other uses including locating enemy submarines or warships.

Using the speed of sound in water (about 1500m/s in the sea, depending on the specific sea-water density). So if there is a delay of 2 seconds between a depth-sounding sonar emitting a pulse and detecting its echo from the sea-bed, the water is 1500 X 2 = 3000m deep.

Harry Hess used sonar and another device still not found. Hey well he actually used an echo sounding device onboard the ship U.S.S Cape Johnson in which he commandered. Hess kept the echo sounding device on throughout his journey and he gained thousands of miles of echo sound maps of the ocean floor. Malkee xx
An echo is a sound wave reflecting off an object. Sonar is a means of detecting object using sound waves, usually echoes.

Echo is a program. '' is not a program. '' does not perform any action. Echo returns what you type. '' does not.
