WebApr 11, 2024 · After the ADC has collected echo and reference channels data, the reference channel is used to calibrate the chirp rate K r of the LFM signal, and then the accurate value of this parameter is used for subsequent processing. In Fig. 5, the dotted line denotes the dechirp reference signal, and its slope is the chirp rate of the signal. The slope ...

WebThe slope of the x 0(x) function, t ” dx 0/dx, is a natural measure of spatial chirp, which we will call the frequency gradient. The other means of parameterization in-volves measuring the beam center position, x 0,of each frequency component, which yields the func-tion, x 0(x). Its slope f ” dx 0/dx is also a valid 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).
