What is chirp bandwidth?
The chirp bandwidth can be straightforwardly computed as the product of βr times the duration of the pulse, i.e., the chirp rate can be expressed as. (5.74) where Br is the transmitted bandwidth and Tp is the duration of the pulse. A linear instantaneous frequency results in a quadratic phase, i.e., (5.75) π π
What is a chirp frequency?
What is frequency chirp? A chirp is a signal in which the frequency increases or decreases with time. This picture shows a linear chirp waveform; a sinusoidal wave that increases in frequency linearly over time.
How do you calculate chirp rate?
Chirp rate for a trapezoidal and raised-cosine pulse type is calculated as: Chirp Rate = Chirp Deviation / pulse width. The maximum Chirp Rate is 80 MHz/uSec: 80 MHz/uSec > Chirp Deviation / pulse width. For example, a pulse width of 0.1 uSec and a Chirp Deviation of 4 MHz has a Chirp Rate of 80 MHz/uSec.
What is a chirp in signal processing?
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.
