Pagination or Media Count:
This report contains analysis of the direction finding DF and fix estimation algorithms in TRAILBLAZER. The TRAILBLAZER software analyzed is old and not currently used in the field. However, the algorithms here analyzed are used in other current IEW systems. The report examines the underlying algorithm assumptions including unmodeled errors and their appropriateness for TRAILBLAZER. Coding and documentation problems are then discussed. A detailed error budget is presented. Keywords Fix estimation Statistical assumptions, Error budget Unmodeled errors Coding errors Peak searching Convergence.
