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.
NO. We call that radar.
Robotic submersibles, sonar, satellites, coring machines, and magnetometers.
Reflection of a transmitted signal is the basic premise of radar and sonar.
Sonars were used to detect any objects that got into the detection field of the sonar. By this, the military could detect enemy submarines etc., which they couldn't see normally because of the opacity and/or darkness of the water.
Naval operations: Submarine and anti-submarine usage. in the thirties a Blimp altimeter called a Sonicaltimeter was tested on Navy Blimps by Admiral Rosenthal, noted (Blimp admiral). The device was made in Germany by Echolot- still in business. Echolot is a blend word of Echo Location or Echo-Pilot. not a Batty idea but uses in a sense ultra-sound not radar waves.
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.

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 is a method of sound based ranging. Therefore as an object it is not subject to an antonym. There is the principal of radar which can also range, but it uses radio waves instead.
Sonar and radar are both used for detecting objects and determining their distance by sending out waves and measuring the time it takes for the waves to bounce back. While radar uses radio waves, which are a form of electromagnetic radiation with longer wavelengths, sonar uses sound waves, which are mechanical vibrations that require a medium to travel through. Both techniques operate on the principle of wave reflection to gather information about the surrounding environment.
