Sonar, Lidar.
No one individual was responsible for improving both (or even either) technology. Radar and sonar were worked on by many investigators over decades to bring them along to the point where they are the effective, reliable tools we look to as we attempt to look at things in the sky, below the water and in the ground. What is arguably the most effective technology in bringing radar and sonar forward is the advancements in electronics, and in computer technology.
SONAR stands for Sound Detection and ranging, and RADAR stands for Radio Aid to Detection and Ranging. as described below (by richard), the principle is simple. Point a signal source in one direction, Listen for the echo to return, and time how long the return signal took, Divide it in two, and with some math, and knowing the speed of the wave, work out how far away the object is. Now if you make the sender/receiver directional. you can move it left and right, and see how wide the object is. If you can rotate it 360 degrees, you get a map of what is arround you. (Gavin)BY sending out a hi frequency pulse to an aircraft and detecting the timing for the return it can be calculate the speed and direction basically location of an aircraft. Sonar has the same principle applied timing of a response return PING to detect the location.Radar is a system that uses radio electromagnetic waves to provide a range to a target normal in air or a vacuum. RADAR propagates its radio waves at the speed of light. Sonar uses sound and propagates in pressure wave through water and the speed of sound. And provides a range to a target in a similar way, just at slow speed.
The basic idea behind radar is very simple: a signal is transmitted, it bounces off an object and it is later received by some type of receiver. This is like the type of thing that happens when sound echo's off a wall. However radars don't use sound as a signal. Instead they use certain kinds of electromagnetic waves called radio waves and microwaves. This is where the name RADAR comes from (Radio Detection And Ranging). Sound is used as a signal to detect objects in devices called SONAR (Sound Navigation Ranging).
The freqeuncy (or pitch) of the sonar is not generally the factor which is likely to effect wildlife, but the amplitude (how loud it is).

NO. We call that radar.
no, radar is used
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.
Sonar and radar's are used by the military, research groups, reconnaissance missions, searches for dead bodies and much more. It is a widely used technology.
they are both used in navigation.
Sonar was not introduced in World War 1.
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.
A special type of radar called sonar is used to detect objects underwater by emitting sound waves and detecting their reflections. Sonar is commonly used in applications such as navigation, communication with submarines, and mapping the ocean floor.
