Nettet21. sep. 2024 · here, C is a linear chirp parameter. Then, we calculate the Fourier transforms of \phi (x,0) as: \begin {aligned} {\widehat {\phi }} (k,0)=\sqrt {2}\root 4 \of {\pi }\exp \left [ -\frac {1} {2}\left ( k-C\right) ^ {2}\right] . \end {aligned} (10) Substituting Eqs. ( 10) and ( 6) into Eq. ( 3 ), we get: In the closed form solution, just presented, the compressed waveform has the standard sinc function response, because a rectangular shape was assumed for the amplitude of the pulse spectrum. In practice, the spectrum of a linear chirp has a rectangular profile only when the time-bandwidth product of a pulse is large, i.e. when T×B exceeds 100, say. When the product is small, the spectral profile of the chirp pulse is seriously degraded by Fresnel ripples as shown in chirp …
