This coordinate system is perfect for my needs -- I have to resample my radial data (Australian radar do equal-degree azimuth sampling, U.S. weather radar don't), but that is easily done.

I have put two images on this site, one generated using visad, and the other using a C++ OpenGL display that illustrates the problem: http://www.nssl.noaa.gov/~lakshman/visad/interpolated.html thanks for all your help.
