Similar Terms: Compressed High-intensity Radar Pulse,CHIRP
CHIRP (Compressed High-intensity >Radar Pulse) is a frequency-modulated sound (sonar) pulse.
Traditional echo sounders rely on a distinct Frequency pulse rebounding off Fish, an object or the bottom, ie 50 kHz, for deepwater Fish finding, or 200 kHz, in shallower water.
The amount of energy required for the signal to reach the bottom in deep water when using a low Frequency signal (say 50kHz), requires a long sonic pulse (possibly 40m in length). Any objects that are closer together than the length of this pulse will not show up as separate objects on the Fish Finder screen.
CHIRP technology modifies the pulse that is sent by the transducer.
Instead of transmitting a distinct pulse beneath the Boat, CHIRP technology modifies the pulse so that a Range of frequencies are transmitted by the transducer; say 28 to 60 kHz, or 130 to 210 kHz, or 42 to 65 kHz. When you transmit a modulated pulse across these ranges, targets that are closer together than a particular pulse length, reflect that pulse at a different Frequency to those further apart than the pulse length, and each will show up separately on the monitor. This Range or pulse sweep is known as the bandwidth, hence the term >Broadband Sonar. The echo signal return from a target, is the same as the Frequency with which the target was struck, so two targets even close together in shallow water will return a slightly different Frequency signal. The result is quite simply, stunningly improved separation and detail.
It can be summed up simply as DEEPER BROADER CLEARER GAME CHANGING TECHNOLOGY.
