The chirp spectrum is a concept often used in signal processing and communication systems, particularly in relation to signals that exhibit a frequency change over time, known as chirps. A chirp signal is characterized by a frequency that increases or decreases linearly (or non-linearly) over time. The chirp spectrum refers to the frequency-domain representation of such chirp signals. Specifically, it describes how the amplitude, phase, and power of the signal vary across different frequencies.
