(U) Airborne Laser Beam Control Technology

Description (U):

(U) In support of Airborne Laser (ABL) beam control technology development, a series of ground field experiments have been completed,
simulating the stressing turbulence conditions and propagation environment expected for the ABL theater missile defense scenario. These
initial experiments used point sources for the adaptive optics and tracking beacons and successfully demonstrated both adaptive optics
compensation and closed-loop tracking performance. These experiments have been repeated with more realistic extended sources
for beacons and with multiple beacon illuminators to mirage scintillation effects on the beacon.
