What is a chirp in signals?

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.

Why do we use chirp signal?

In general, chirp generation can involve linear or nonlinear phase modulation that modifies the instantaneous frequency. Linear chirp is used because the signal processing required once the pulse is received is simpler to implement and can occur faster in the radar transceiver or DSP block.

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.

How do you make a chirp signal?

One approach to generate a chirp signal is to concatenate a series of segments of sine waves each with increasing(or decreasing) frequency in order. This method introduces discontinuities in the chirp signal due to the mismatch in the phases of each such segments.
