High Performance Nb3Sn (Ta)Wires by Tin Enrichment and Increased Filament Content

Not Available The development of a completely passive technique for non-cooperative identification (NCID) of aircraft using a spaceborne, polarimetric hyperspectral imaging sensor is proposed. In addition to being passive, with the accompanying 1/r^2 standoff advantage compared to active methods, the proposed technique uses the observables, degree of linear polarization and angle of linear polarization, which have been shown by us in computer simulations to capable of yielding high probabilities of classification (>80%) even for visually similar aircraft such as the F14 and F15. The proposed effort makes use of Aerodyne's infrared polarimetric hyperspectral imaging sensor (IRPHSI) which uses a novel time-simultaneous polarimetric measurement technique which yields perfectly spatially registered polarimetric measurements. The time-simultaneity of the technique allows operation in the sub-pixel regime, which is essential for practical spaceborne applications, possible. The proposed effort consists of formulating a test plan for collection of surface-based field data with the IRPHSI sensor, extension of our existing air-to-air NCID performance analysis to spaceborne configurations, collection of field data, and quantification of the passive NCID effectiveness.
