2. Chirp - Wikipedia

   en.wikipedia.org/wiki/Chirp

   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 . [ 1 ] It is commonly applied to sonar , radar , and laser systems, and to other applications, such as in spread-spectrum communications (see chirp spread spectrum ).

3. Chirp spectrum - Wikipedia

   en.wikipedia.org/wiki/Chirp_spectrum

   The stationary phase method does not predict or deal with Fresnell ripples, so it is unable to offer any means by which these ripples can be minimized. As an example, the figure below shows a chirp spectrum with T. Δ F =250 obtained for a non-linear chirp aiming to match the Hamming window, using the methods described above. The figure shows ...

5. Chirplet transform - Wikipedia

   en.wikipedia.org/wiki/Chirplet_transform

   Although chirp signals have been known for many years in radar, pulse compression, and the like, the first published reference to the chirplet transform described specific signal representations based on families of functions related to one another by time–varying frequency modulation or frequency varying time modulation, in addition to time ...

6. Chirped pulse amplification - Wikipedia

   en.wikipedia.org/wiki/Chirped_pulse_amplification

   One or multiple reflections between a pair of chirped mirrors or similar device allow any form of chirp. This is often used in conjunction with the other techniques to correct for higher orders. The Dazzler is a commercial pulse shaper in which light is diffracted from an acoustic wave. By tuning the timing, frequency, and amplitude of the ...

7. Chirp mass - Wikipedia

   en.wikipedia.org/wiki/Chirp_Mass

   In astrophysics, the chirp mass of a compact binary system determines the leading-order orbital evolution of the system as a result of energy loss from emitting gravitational waves. Because the gravitational wave frequency is determined by orbital frequency, the chirp mass also determines the frequency evolution of the gravitational wave signal ...
