TFSO LONG-PERIOD L-ARRAY NOISE COHERENCE
Abstract
Three long-period noise samples recorded at the TFSO L-array were analyzed for coherence properties. The results indicate that the ordinary coherence is generally high between elements 5-10 km apart and low between elements further apart. Multiple coherence is high for the first noise sample but low for the third sample. Zero-delay noise summations for an additional sample produce about N to the 1/2 power improvement over the average RMS noise level and beamforming of a large P-wave signal produces about N to the 1/2 power improvement in signal-to-noise ratio.
