RADIATION NOISE ESTIMATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a radiation noise estimation device for performing radiation noise estimation with high accuracy in preliminary measurement and capable of minimizing a cost and a time relating to actual measurement while preventing rework in the actual measurement.SOLUTION: The radiation noise estimation device includes: an initial value setting part 2 for calculating a combination (hereinafter, referred to as "a radiation source model") of a plurality of minute radiation sources having the same radiation characteristics as radiation noise detected at a position separated at a predetermined distance from a radiation source as target equipment; an actual radiation noise measurement part 3 for measuring actual radiation noise detected by an antenna installed at a position separate at a predetermined distance from the radiation source; a radiation source model calculation part 4 for calculating a first radiation source model, and a second radiation source model to an n-th radiation source model; a distribution processing part 5 for arranging the models in a two-dimensional distribution diagram; an exclusion processing part 6 for excluding the radiation source model deviated from a concentration region concentrated in the two-dimensional distribution diagram; and an extraction part 7 for extracting the radiation source model that satisfies predetermined conditions.
