chirp transform

The chirp transform is a mathematical technique used to analyze signals whose frequency changes over time, such as a siren or music note that rises and falls. Unlike traditional methods that look at a static frequency, the chirp transform accounts for these changes by effectively "tracking" the signal's frequency evolution. This allows for better detection and analysis of signals with varying frequencies, making it useful in areas like radar, sonar, and communications. In essence, it's a way to better understand signals that are not constant but dynamically changing in frequency.
