2.4 Sonar technology

Traditional sonar technology

Traditional 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 technology

CHIRP sonars use a swept frequency 'CHIRP' signal
which can distinguish between multiple close targets,
this enables the sonar to display multiple targets
instead of large combined targets that you would see
when using traditional non-CHIRP sonar.
Benefits of CHIRP include improvements to target
resolution, bottom detection even through bait balls
and thermoclines and detection sensitivity.
