Abstract : This document is the User's Guide and Reference Manual for GENAH, the Generalized Nearfield Acoustical Holography processing program. The User's Guide provides instructions for operating the GENAH programs. This includes installing and running the code, choosing input parameters and a discussion of the input and output file structure. The Reference Manual contains material explaining the theory of cylindrical nearfield holography and how this theory is implemented in the GENAH code. Sufficient detail is provided to allow a user with an operating knowledge of FORTRAN-77 to diagnose and alter the code to suit local needs. Appendices are included detailing the file formats, the file header, a list of operator inputs to GENAH, a list of all routines needed to compile and run the GENAH code, and a discussion of wavenumber filtering in holography.
