Title:
TIME HISTORY SIGNAL PROPAGATION PREDICTION DEVICE
Document Type and Number:
Japanese Patent JP3142379
Kind Code:
B2
Abstract:
PURPOSE: To obtain a time history signal propagation prediction device capable of predicting the observation state of a time history signal emitted from a complicated signal source at an arbitrary position and an arbitrary time.
CONSTITUTION: Provided is a storage device 12 storing each vibration signal data obtained at each small separation surface which is a plurality of separated small surface of each body of vibration signal source and each signal amplitude data at a certain time. Also provided are a split calculation device 13 calculating the true signal vibration value of vibration signal generated in each small separation surface itself at the time by substituting each vibration signal data stored in the storage device 12 and each signal amplitude data in a predetermined corelation, and a synthetic calculation device 14 calculating the signal propagating to an arbitrary position and an arbitrary time by substituting the true signal amplitude obtained with the split calculation device 13 and the vibration signal data in the predetermined corelation.
