METHOD AND DEVICE FOR MEASURING ELECTRIC FIELD INTENSITY

PROBLEM TO BE SOLVED: To improve efficiency of measuring by detecting the receiving electric field intensity of a receiving antenna with a mobile measuring apparatus on a carriage with wheels and storing a present measured position and the electrical intensity to a controller. SOLUTION: Electrical field intensity received with a receiving antenna 1 is measured with a measuring apparatus 2 to detect a measured spot with a position detector 3. A controller 4 controls the measuring apparatus 2 and the detector 3 and stores measured data. A power source is supplied to them with a battery 5, the whole is mounted on a carriage 6 with wheels and moved therewith. While the carriage 6 is moved, the electric field intensity is measured to detect a present position, and the measured data are stored to the controller 4. The electric field intensity is two-dimensionally easily found from the data file. Thus, since the electric field intensity is measured while the carriage is moved, electric field distribution of a space can easily grasped and efficiency of measuring can be improved.
