Paper Abstract

ABLE ACE was a high-altitude, laser-propagation experiment in which a series of measurements were made of laser propagation between two aircraft flying at 13 to 14 km altitude and at up to 200 km separation. The measurements included a pupil plane scintillation image, an atmospheric tilt sensor, a wavefront sensor, and a differential phase measurement, across a 50 cm aperture. In addition, a small- aperture, high-bandwidth scintillometer and simultaneous aerothermal-probe measurements were made. The purpose of these measurements was to validate wave-optics propagation codes for high-altitude, long horizontal-path propagation, and to better understand what parameters were important to include in the codes. Additionally we sought to directly understand laser propagation characteristics in the regimes of the flights. This paper provides an overview of ABLE ACE. It discusses the sensor suite, the missions, and the code validation methodology as well as the conclusions of the program.
