[Moon-net] Parabola Model, Pattern generation; with Random surface errors

Folks: 

Are there any Antenna modeling programs, within reach of EME enthusiasts ( If not them, then avaailable for professional work)  that would allow you to enter a fine detail theoretical  surface coordinate database, then have the user apply an empirically derived RMS error metric, to the perfect coordinate database, generating a representative, as found, surface?   

Then, based on the real, "lumpy" surface, generate beam patterns, for a given frequency.  It would be interesting to see Jamesburg's real pattern, both at C band, it's designed frequency, and then pushing it to higher frequencies, say, X band, and see how the pattern degrades, based on an RMS error which we determined to be in the vicinity of .050"





All the best,
