Sonar technology ContentsTraditional sonar technologyTraditional sonar uses a single carrier frequency or carrier wave for the sonar ping. The sonar works by measuring the time it takes the ping echo to return to the transducer to determine target depth.CHIRP technologyCHIRP (Compressed High Intensity Radar Pulse) sonar uses a swept frequency signal covering a wide range of frequencies which produces more accurate images with higher detail than traditional sonar.Parent topic: Sonar technology overviewNext topic: Sonar overview
