Time-frequency equivalence using chirp signals
11 mar 2021 · A chirp signal is a signal with time-varying frequency The generic form of chirp signals for electrochemical system analysis Computers |
What is the expression of a chirp signal?
The generic form of a chirp signal is u(t) = A sin(φ(t)) where φ(t) is the instantaneous phase.
The instantaneous angular frequency of the signal at any instant t is defined as the differential of the instantaneous phase of the sinusoid at time t (ω(t)=2πf(t) = dφ(t)/dt).11 mar. 2021What is the purpose of chirp signal?
Chirp signals are an ingenious way of handling a practical problem in echo location systems, such as radar and sonar.
Figure 11-9 shows the frequency response of the chirp system.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 chirping in signal processing?
A chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time.
In some sources, the term chirp is used interchangeably with sweep signal.
