D -- ATMOSPHERIC PROPAGATION ANALYSIS SOL DASW01-98-Q-0487 DUE 062298 POC Al Moore, (703) 693-2139 E-MAIL: mooralj@hqda.army.mil, mooralj@hqda.army.mil. The Defense Supply Service-Washington, on behalf of the Office of the Secretary of Defense (OSD), Program Analysis and Evaluation (PA&E), has a requirement for the performance of studies in assisting PA&E's Strategic Defensive and Space Programs Division in evaluating the Airborne Laser (ABL). The Government requires that the contractor apply existing computer models to analyze atmospheric propagation issues associated with the ABL. Where appropriate, the contractor shall modify and improve these models and supplement them using statistical analyses or other mathematical techniques. PA&E requires independent assessments of technical concepts and designs of ballistic missile defense systems. The objective is to evaluate selected alternatives and technical issues in support of OSD's role in both the PBBS and the process for acquiring major systems. The contractor will analyze various methods of calculating atmospheric turbulence and the impact of turbulence of effective range. The contractor will also examine the expected performance of current and projected adaptive optical systems to compensate for atmospheric turbulence. Finally, the implications of turbulence on the effectiveness of beacon and tracking illuminators will be assessed. Analytical techniques will be matched to the problem at hand and the level of detail required to resolve the issues. A high degree of specialized technical expertise will be required to execute the tasks successfully. The contractor will deliver technical notes and/or briefings upon completing each task. This is a one time requirement and the overall level of effort for this requirement is estimated at 160 staff hours. Contact Al Moore (703)-693-2140 to request a copy of the RFQ, DASW01-98-Q-0487.
