ELECTRIC FIELD INTENSITY MEASURING DEVICE AND ELECTRIC FIELD INTENSITY MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To accurately measure the electric field intensity distribution of an electric wave outputted from a road side wireless device.;SOLUTION: An electric field intensity measuring device 10, upon detecting a signal 41 outputted from a vehicle detector 40, starts measuring the electric field intensity of the electric wave outputted from a road side wireless device 30. The electric field intensity measuring device 10 measures a distance moved from a position where a signal 41 outputted from the vehicle detector 40 is detected, and finishes the measurement of the electric field intensity when the measured distance reaches a pre-designated designation distance.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
