測定プログラム、及び測定システム
Document Type and Number:
Japanese Patent JP6965148
Kind Code:
B2
Abstract:
To accurately and efficiently measure the distance between a base station and a moving body.SOLUTION: Based on the radio field strength from a moving body 10 measured by base stations 12A, 12B, 12C in order to reduce the error due to fluctuation components such as noise and the radio field strength from the base station measured by the moving body, the radio field strength is filtered and processed (change of the radio wave strength equal to or more than a predetermined threshold, out of the radio field strength, is cut, the moving body is averaged, and scale conversion is performed). Based on the filtered and processed radio field strength, the distance between the base station and the moving body is measured.SELECTED DRAWING: Figure 3
