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.
