Radiation disturbance measurement method and radiation disturbance measurement system

摘要

The radiation disturbance measurement method is a temporary measurement that performs a wide band measurement that is a measurement including peak detection and quasi-peak detection for the measurement frequency range by one fast Fourier transform by the EMI receiver (16). Step (S21), a calculation step (S22) for calculating the difference between the peak level and the quasi-peak level obtained for the measurement frequencies to be candidates for the measurement result, and the obtained difference being the measurement frequency In the determination step (S23) of determining whether it is less than a predetermined reference value corresponding to the above, and when it is determined that the difference is less than the reference value, the results obtained in the wide band measurement Output as a level (S24), and if it is determined that the difference is above the reference value, fast Fourier transform by the EMI receiver (16) targeting the measurement frequency in the frequency range narrower than the measurement frequency range It performs narrowband measurement is the measurement, the results obtained are outputted as an interference level of the radiation interference wave (S25) and an output step.
