Chirp sweep time
WebFor a chirp waveform that sweeps over a frequency range F1 to F2 in a time period T, the nominal bandwidth of the pulse is B, where B = F2 – F1, and the pulse has a time-bandwidth product of T×B. Following pulse compression, a narrow pulse of duration τ is obtained, where τ ≈ 1/B, together with a peak voltage amplification of √ T×B . http://www.ece.northwestern.edu/local-apps/matlabhelp/toolbox/signal/chirp.html
