摘 要：This paper describes a methodological trial from a basic viewpoint based on the system theoryand its simulation for the environmental noise and vibration *** state estimation of non-stationarily vibratory structure system through the observation of radiated noise accompanied withundesirable other vibration and background noise is discussed *** recursive estimation algo-rithm is newly derived by expanding the so-called Bayes’theorem in the form of an orthogonal expan-sion ***,any kinds of statistics of state variables can be derived from this estimatedprobability density *** validity and the effectiveness of proposed method are confirmedespecially by means of digital simulation,since the present study is yet in an early stage and focussedon only the methodological viewpoint in this paper.
