What is chirp duration?

Spectrogram of a linear chirp. The spectrogram plot demonstrates the linear rate of change in frequency as a function of time, in this case from 0 to 7 kHz, repeating every 2.3 seconds. The intensity of the plot is proportional to the energy content in the signal at the indicated frequency and time.

How do you calculate chirp?

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 a chirp waveform?

A chirp is a signal in which the frequency increases or decreases with time. This picture shows a linear chirp waveform; a sinusoidal wave that increases in frequency linearly over time.

What is a quadratic chirp?

If a linear relationship exists between frequency and time, the chirp is known as a linear frequency mod- ulated (LFM) chirp. A quadratic relationship between frequency and time results in a quadratic frequency modulated (QFM) or quadratic chirp signal.
