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.
sOUND NAVIGATION AND RANGING
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.
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.
Henry Hess did not invent sonar or radar. Sonar was first developed in the early 20th century by several scientists, including Lewis Nixon and Reginald Fessenden, while radar was independently developed by various scientists in the 1930s, such as Sir Robert Watson-Watt and his team in the UK.

RADAR - Radio Detection and Ranging SONAR - Sound Navigation and Ranging
Ultrasound is sound which has a frequency higher than that of audible sound.( like radar )ADDED: Not like radar. That uses radio waves, although sonar and radar principles are similar.
Sonar, Lidar.
They are similar to radar or sonar. They evaluate attributes of a target by interpreting the echoes from radio or sound waves respectively.
NO. We call that radar.
no, radar is used

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.
