WebJul 18, 2024 · A chirp signal in which the frequency continuously increases (up-chirp) or decreases (down-chirp) with time as shown in the picture below. It is commonly used in sonar and radar applications, but has other applications such as stimulus response analysis and spread spectrum communications. 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 more The basic definitions here translate as the common physics quantities location (phase), speed (angular velocity), acceleration (chirpyness). If a waveform is defined as: See more A chirp signal can be generated with analog circuitry via a voltage-controlled oscillator (VCO), and a linearly or exponentially … See more Chirp modulation Chirp modulation, or linear frequency modulation for digital communication, was patented by Sidney Darlington in 1954 with significant later work performed by Winkler in 1962.
