Abstract
This document describes two areas of enhancement to the software program PRODAT as performed by PRIOR Data Sciences. The first area is the addition of X-Windows display routines which display lofargrams and spectra on on-MASSCOMP machines. These routines make use of the Sonar Display Utility (SDU) library of X-Windows routines. The second area of development was the addition of the Clutter Tool. This tool allows a user to select points and lines on a lofargram display to assist in the analysis of narrowband ambient noise. The addition of this functionality required changes to the SDU library routines which are also described. This report documents the functionality, design and implementation used in creating these additions to the PRODAT software. The Clutter Tool user manual which is an Appendix of the PRODAT user manual is also included for reference.
