WebSep 1, 2024 · A chirp excitation pulse is understood as concatenation of three rotations which satisfy . Lets see how. Given the Bloch equation, where X is the magnetization vector, the chirp pulse has instantaneous frequency where a is the sweep rate and phase . The frequency is swept from , in time with offsets in the range . http://www.rfcafe.com/references/electronics-world/chirp-new-radar-technique-january-1965-electronics-world.htm
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 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.
