摘要： PROBLEM TO BE SOLVED: To carry out calibration work without stopping an operation. SOLUTION: This system is provided with a sensor part 10 containing a plurality of sensors, a calibration signal generating part 60 for generating a calibration signal, a calibration signal supplying part 20 for selecting the sensors in order from the sensor part and for supplying the calibration signal generated in the calibration signal generating part to a signal route through which the signal from the selected sensor flows, a calibration processing part 51 for finding a characteristic of the signal route to which the calibration signal is supplied by the calibration signal supplying part, using a prescribed characteristic as a reference, a reception processing part 52 for processing the signals transmitted from the signal routes of the sensors other than the selected sensor from the sensor part, after correcting it based on the characteristic found in the calibration processing part, and a direction search processing part 53.
