Abstract

A vertical planar array of 32 microphones (eight elements in the vertical direction and four in the horizontal; overall dimensions approximately 6 m by 3 m) was used to image the scintillations and angle-of- arrival fluctuations from a source 770 m distant. Data sets of 20-min duration were collected in a variety atmospheric conditions. On a windy afternoon, the source image underwent dramatic scintillations and fluctuations in its apparent position. For still nighttime conditions, the image was much more stable, although deep fading still occurred.
