Acoustic phased arrays for the detection of nuclear bursts in the atmosphere

T. F. Burke

ResearchPublished 1965

A discussion of the possible use of phased arrays in detecting the acoustic signal from atmospheric nuclear bursts. This Memorandum considers, for simple unshaded square plane arrays, the dependence of array gain upon frequency, azimuth, size of array, number of sensors in the array, and uncertainty in local velocity of sound. The author concludes that the use of phased arrays of omni-directional acoustic sensors would significantly improve both the signal-to-turbulent-noise ratio and the signal-to-acoustic-noise ratio.
