Title:
SIGNAL PROCESSING DEVICE AND SIGNAL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2014/175442
Kind Code:
A1
Abstract:
A signal processing device is provided with a propagation speed calculation means for calculating the intensity and direction of vibrations in an underground structural area using a calculation model that includes vibration propagation speed data, a simulated propagation speed calculation means for inputting vibration source information into the calculation model using a simulated signal input means and calculating the intensity and direction of the vibrations in the underground structural area using the calculation model, and an update amount calculation unit for calculating, on the basis of propagation speed distribution information and simulated propagation speed distribution information, an update amount by which to update the calculation model. The calculation model is a solid model. The propagation speed calculation means calculates the intensity and direction of a first vibration using a first measurement signal input into the calculation model and calculates the intensity and direction of a second vibration using a second measurement signal input into the calculation model.
