I have a Gaussian pulse with a nonlinear chirp:
$$ e^{-t^2} Cos(50 t - 8πe^{-2t^2} ) $$ or in a general form: $$ e^{-t^2} Cos(a t - b e^{-2t^2} ) $$
My problem is to find the Fourier transform of this formula in an analytical form. Thanks a lot in advance.
One related numerical solution is here: https://mathematica.stackexchange.com/questions/99670/how-to-calcualte-the-fourier-transform-of-a-guassian-pulse-with-a-nonlinear-chir：
