The most straightforward way, I think, is to convert your
polar coordinates to XY coordinates and grid, if necessary,
before contouring.

If you mean you would like your contour plot in a circular
type plot, then I have had some luck converting coordinates
to latitude/longitude coordinates and drawing the contours
on a circular map projection.

Cheers,

David
