Sonarteknikker refers to the various methods and technologies used to produce and interpret sonar signals. Sonar, an acronym for Sound Navigation and Ranging, utilizes sound waves to detect objects, determine their distance, and map underwater environments. Active sonar systems emit sound pulses and listen for the echoes that return after reflecting off objects. The time it takes for the echo to return, along with the frequency shift (Doppler effect), provides information about the target's range, speed, and direction. Passive sonar systems, on the other hand, do not emit sound but instead listen for sounds produced by other sources, such as ships or marine life. This technique is often used for covert surveillance and identification.
Different types of sonar utilize distinct transducer configurations and signal processing techniques. For instance, side-scan sonar
