1. A calibration device for calibrating observation data received by a plurality of sensors, the calibration device comprising:
- an observation data vector generation processing part that receives the observation data from the plurality of sensors to generate an observation data vector from the received observation data;
a mode vector association processing part capable of calculating or storing in advance a mode vector corresponding to the observation data vector, and of calculating or storing in advance a Fourier coefficient for calculating an orthogonal vector to the mode vector; and
a calibration parameter calculating part that acquires the observation data vector from the observation data vector generation processing part, acquires the mode vector and the Fourier coefficient corresponding to the acquired observation data vector from the mode vector association processing part, calculates the orthogonal vector to the mode vector from the acquired mode vector and the acquired Fourier coefficient, and calculates a plurality of calibration parameters for calibrating an observation error included in the observation data vector from the calculated orthogonal vector and the observation data vector.

Abstract
In a calibration device, a calibration matrix calculation processing part estimates a calibration matrix by using an orthogonal vector stored in an orthogonal vector storage part and an array mode vector stored in an array mode vector storage part. A calibration matrix output part transmits the calibration matrix computed by the calibration matrix calculation processing part to an unknown parameter estimation device.
