LARGE-ARRAY SIGNAL AND NOISE ANALYSIS
Abstract
Analysis of eight 80-minute noise samples, recorded during the period 29 March to 7 October 1967, has been completed. Four of these samples were recorded consecutively thereby forming a 320 minute long noise sample. The analysis includes power density spectra, multiple coherencies, and wavenumber spectra. In general, the summer noise appears similar in character to previously analyzed winter noise samples. The only usable microbarographic data was recorded by an instrument located within 50 feet of the Ao sensor and simultaneous with the 320 minute long noise sample. As expected, the power density of the pressure decays exponentially with increasing frequency. No significant coherence was found between the pressure and the Ao vertical seismometer output.
