The radar-sensor performance, such as chirp bandwidth , chirp slope, and frequency-modulation (FM) linearity, are determined by the FMCW chirp generator.

Chirp Quality Measurements in Radar Applications

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.
