Measurements and analyses of infrasound noise field in the atmosphere

Methods for measuring and analyzing the infrasound noise field in the atmosphere have been expounded. A set of space correlation radii of noise corresponding to wind speed 4 m/s has been obtained, which can be taken as the tentative basis for an acoustical array design. At the same time, the wind speed-sound pressure relation curves have been measured and calculated, and the antijamming ability of the array receiving infrasonic signals is obtained.
