chirping
All > Technology > Telecommunications
- The rapid changing, as opposed to long-term drifting, of the frequency of an electromagnetic wave. Note: Chirping is most often observed in pulsed operation of a source. 2. A pulse compression technique that uses (usually linear) frequency modulation during the pulse.
