How to plot a function in spherical coordinates?

I want to plot the followig function in spherical corrdinates with alpha=0-pi, and beta=0-2*pi. P11 and P12 are row vectors in my directory. P11 is dependent on angle alpha while P12 on angle beta.

The figure I need to obtain is given as

Hi,

I understand that you're trying to plot spherical coordinates.

You may want to try: 3D Polar Plot

Thanks

Actually not. What I want is to plot this function on a sphere to obtain the figure mentioned in the question below which is exactly obtained from the same function with a slight different parameter values.
