Abstract
The goal of this project was to further enhance the capabilities of the AVAST software. The main application was extended to support multi-bistatic ray tracing analyses. The existing field point generation methods were consolidated, new field point generation and management methods were implemented, and all field point generation methods were made available for use with all AVAST solvers and sonar scenarios. Options for more realistic modelling of flat panel reflection were investigated. A new, more efficient process management algorithm was implemented in both the Windows and Linux versions of the software. The various software components were made more stable and updated to provide the user with better feedback. Some areas for further study and improvement were also noted, with further study of flat panel reflection modelling and updates to the user interface identified as requiring particular attention.
