What is meant by frequency chirp?

What is frequency chirp? 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.

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 chirp effect?

Chirp is a sudden change of the center wavelength of a laser, caused by laser instability. A chirp is a signal frequency that increases over time, called “up-chirp,” or decreases, called “down-chirp.” In some sources, the term chirp is used interchangeably with sweep signal.

What does chirp stand for?

CHIRP stands for “Compressed High Intensity Radar Pulse.” That's a fancy way of saying it can show you fish that other forms of 2D sonar can't.
