Chirp measurement
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. It is commonly applied to sonar, radar, and laser systems, and to other applications, such as in spread-spectrum communications (see chirp spread spectrum). This signal type is biologically inspired and occurs as a ph… WebAug 26, 2010 · Chirp measurements depend on determinations of pulse position, timing, cardinal points, and carrier frequency offset.
