Airborne Laser Systems Testing and Analysis (essals et analyse des systemes laser embarques)

摘要

This AGARDograph presents state-of-the-art methods for evaluating the performance of laser systems operating in the infrared with different operational and environmental conditions. Results of the PILASTER (PISQ LASer Test and Evaluation Range) research and development program, conducted by the Italian Air Force Flight Test Centre in collaboration with the Defence Academy of the United Kingdom (Cranfield University) are presented. For aircraft experimental activities with laser systems, it is important to define test missions representative of different operational scenarios and to verify systems performance in realistic environments. Laser technology status and future technology trends are investigated, in order to determine the relative strengths and weaknesses of these technologies when applied to airborne systems. Mathematical models for laser beam propagation, mission geometry analysis, target reflectivity and detection are identified. Safety issues are analysed in the light of the operational requirements and human eye safety for airborne laser systems and guided weapons. Technical characteristics of the PILASTER range instrumentation are identified. Finally, the requirements associated with tactical and test/training mission planning are defined with the kernel algorithms of suitable simulation programs capable to assist aircrews and flight test engineers in the determination of optimal aircraft flight profiles.
