Scattered particle estimation device, scattered particle estimation method and scattered particle estimation program

摘要

PROBLEM TO BE SOLVED: To easily estimate the existence of scattered particles which affect radio wave propagation in wireless communication. SOLUTION: In a scattered particle estimation device that estimates the presence of scattered particles that cause a loss in the propagation of a radio signal, the power intensity of the radio signal transmitted from a transmitting station to a receiving station via a plurality of propagation paths is propagated. Based on the measurement unit that measures each and the reference power intensity of the radio signal measured for each propagation path when there are no scattered particles, the fluctuation amount of each power intensity measured by the measurement unit is calculated for each propagation path. The range estimation unit that estimates the existence range of scattered particles based on the calculation unit and the fluctuation amount calculated for each propagation path by the calculation unit, the existence range of scattered particles estimated by the range estimation unit, and the calculation unit It has a density estimation unit that estimates the density at which scattered particles are present based on the calculated fluctuation amount.
