Obtaining a horn feed parabolic reflector far field propagation pattern

I have a horn antenna working at 144GHz with A=12mm and B=14mm. Then I'll illuminate a satellite dish of 57cm diameter with this antenna, with the feed located at the focal point of the parabola. I have the radiation pattern of the horn, made with MATLAB.
The goal is to know the beam propagation (power radiation) pattern of the parabola in the far field, basically when it hits the receiver at the end of the wireless link. I don't know how doing it, I mean, how to find the radiation pattern of the parabola in such a configuration. I wanna be sure about the beam profile, whether it's parallel or diffracts or is Gaussian through the path, in order to realize the receiving aperture.
Any hint and comment would be of great help.
Thanks in advance
