Assignee: YOKOGAWA ELECTRIC CORPORATION
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 9:
10. The magnetic detector according to claim 1, wherein,
the signal generator sweeps a sine wave pulse as the incident wave and inputs the sine wave pulse to the transmission line; and
the calculator obtains an amplitude and a phase difference of the reflected wave to the incident wave for each frequency of the incident wave swept and input, generates frequency domain data of reflectance based on the amplitude of the reflected wave to the incident wave, generates frequency domain data of phase difference based on the phase difference of the reflected wave to the incident wave, and generates time domain data of the reflected wave through an inverse Fourier transform of the frequency domain data of reflectance and the frequency domain data of phase difference to calculate the position and the strength of the magnetic field applied to the transmission line.
