Chirp sweep
WebThe chirp/FFT measurement is a fast and powerful method for measuring the frequency response of linear systems. Speeding up the frequency response measurement matters, e.g. for imaging applications such as laser scanning vibrometry, due to the large number of spectra that need to be acquired.

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 ramping control voltage. It can also be generated digitally by a digital signal processor (DSP) and digital-to-analog converter (DAC), … See more • Chirp spectrum - Analysis of the frequency spectrum of chirp signals • Chirp compression - Further information on compression techniques • Chirp spread spectrum - A part of the wireless telecommunications standard IEEE 802.15.4a CSS See more Linear In a linear-frequency chirp or simply linear chirp, the instantaneous frequency $${\displaystyle f(t)}$$ varies exactly linearly with time: See more A chirp signal shares the same spectral content with an impulse signal. However, unlike in the impulse signal, spectral components of the … 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.

WebAn ionosonde, or chirpsounder, is a special radar for the examination of the ionosphere. The basic ionosonde technology was invented in 1925 by Gregory Breit and Merle A. Tuve [1] and further developed in the late 1920s by a number of prominent physicists, including Edward Victor Appleton.
