Mapping spherical antenna patterns to 2D contour plots
--------------------------------------------------------------------------------
I'm fighting, trying to take 3D spherical antenna pattern data and plot it to a 2D contour plot. I can do the everyday spherical transformation map to a x-y plot, but the contours are funny and not lining up so like a tradition contour map.... I need the projection equations... Any references or hints? I've seen these plots in a U V space plot..
I guess an extension of the x = sin cos, y = sin sin, z = cos formulas...
Any help?
Thanks
