If you can compile AIPS code then there is a thing we call a paraform 
task.  The relevant one is UVFIL.  Take a look at its help file and the 
code itself (in $APGNOT).

There is a detailed memo I just wrote - AIPS Memo 117 available from our 
web site which may help with some details in FITS and things like 
antenna tables and such.

The tasks DTSIM and UVCON would be best if they can be used.
