ELECTRIC FIELD MEASURING APPARATUS AND ELECTRIC FIELD MEASURING METHOD FOR USE IN THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an electric field measuring apparatus that can improve detection sensitivity by performing appropriate signal processing on a receiving signal from a sensor without performing hardware conversion such as enlargement of an electric field sensor.;SOLUTION: The electric field measuring apparatus includes a signal generator (1) for generating an RF pulse signal, an amplifier (2) for amplifying the RF pulse signal generated by the signal generator, an antenna (3) for radiating the RF pulse signal amplified by the amplifier toward free space, a photoelectric field sensor system (4) for detecting the electric field intensity of the signal radiated from the antenna, a measuring unit (5) for measuring an RF signal corresponding to the electric field intensity output from the photoelectric field sensor system, and a correlation processor (6) for performing correlation processing on the detection signal of the measuring unit.;COPYRIGHT: (C)2011,JPO&INPIT
