I have a following issue. I have a formula of Array Factor. It looks like:
$$AF (\phi) = I_{0} \cdot \exp[j\cdot b\cdot\omega_{0}\cdot(\cos(\phi-\phi_{0}) - \cos(\phi_{w}-\phi_{0}))]$$
$I_{0}, b, \phi_{0}, \phi_{w}$ are constants.
Now i need to calculate Fourier transform of it (transition from "angle" domain to "frequency" domain).
I know a correspondent of $exp(j\cdot\omega_{0}\cdot t)$ (that's a two Dirac functions) - in my case i use angle instead of time, but it doesn't matter.
But the problem is that in my case i have deal with $exp(j\cdot\cos(\phi)\cdot \omega)$ and can't see a possible way to solve it.
Any suggestions?
Thanks for your help
