Chirp in radar
Did you know?
WebChirp waveforms are commonly used in automotive radar and other sensor applications to provide the required information for calculating range and Doppler velocity of objects in a scene from the radar returns. An example is a frequency modulated continuous wave (FMCW) radar, which transmits a sequence of chirps within a frame as shown in Figure 1. WebChirp, or Chirp Spread Spectrum (CSS), is a long-range radio-frequency technology for wireless communication that can be leveraged to detect and track the location of people, assets, and devices both in and outdoors, across large-scale facilities.
