A trial of dynamical method for detecting acoustic signals contaminated by random background and wind-induced noises based on the information on wind velocities and its applications to the field measurement

摘要

A wind-induced noise influenced the acoustic measurements in the outdoor environment especially in the measurement of low frequency acoustic signals. In this paper, a new trial of dynamical countermeasure method for the wind-induced noise will he proposed by considering the effective usage of the successive information of wind velocities. By expanding the multivariate moment generating functions in the statistically orthogonalized series form, the generalized multi-variate regression model of the wind- induced noise on the wind velocisies and the dynamical computer-aided algorithm for estimating the unknown acoustic signals from Bayesian viewpoint will he newly derived.
