Radar is an acronym for what? What does radar do?
Radar is an acronym for radio detection and ranging. A radar system transmits a radio beam, then detects and measures the echo when the beam bounces off an object. This provides information about both the target's direction and range.

T/F: Radar cannot track the object if deceleration is greater than one mph/second.
True

Sonar is an acronym for what? What does sonar do?
Sonar means "sound navigation and ranging." Sonar uses sonund waves to determine the location, size, and relative motion of underwater objects. Sound waves emitted by or reflected from an object are picked up by sonar equipment and are analyzed for the information they picked up.

What are the three types of sonar, and what do they do?
Active- sends out a noise to be reflected off of a target to find it's distance.
Passive- receives noise that can be emitted form a ship, submarine, or even a whale. Acoustic- allows two objects to communicate. |
