Because these signals mimic sines that are swept in time, they are known generically as swept sine chirps 2 A sine signal is generated at one frequency, the response is measured at that frequency, and then the signal is changed to another frequency

What is the frequency range of chirp?
CHIRP technology began filtering down to recreational sonars in about 2009. CHIRP fishfinders transmit a longer pulse than traditional sonar, putting more energy into the water column, with a true broadband frequency range of up to 117kHz.How do you calculate chirp rate?
Chirp rate for a trapezoidal and raised-cosine pulse type is calculated as: Chirp Rate = Chirp Deviation / pulse width. The maximum Chirp Rate is 80 MHz/uSec: 80 MHz/uSec > Chirp Deviation / pulse width. For example, a pulse width of 0.1 uSec and a Chirp Deviation of 4 MHz has a Chirp Rate of 80 MHz/uSec.What is chirp response?
The impulse response is an oscillatory burst that starts at a low frequency and changes to a high frequency as time progresses. This is called a chirp signal for a very simple reason: it sounds like the chirp of a bird when played through a speaker.- Range resolution = (pulse length x velocity of sound) / 2
In a conventional Tritech system the smallest pulse length is 50 micro seconds and velocity of sound in water (VOS) 1500 metres/second (typical). Therefore our range resolution = 37.5mm.
