Abstract: PURPOSE: A method for inferring radio refractive index is provided to estimate a radio refractive index according to heights using an electric wave characteristic by estimating an accurate refractive index and simplifying a receiving structure. CONSTITUTION: A path loss measuring result is obtained(301). For the above process, a transmission side changes set frequencies and transmits the changed frequencies, and a receipt side measures a path loss corresponded to each frequency using one antenna. A path loss result is forecasted in the same band as a frequency used in a measuring process using an electric wave model having a refractive index profile of an atmosphere as a variable(302,303). A similarity between a path loss measuring result and a path loss forecasting result is judged(304). In the case that a judgement function is approached to '1', that is, a fixed condition is satisfied, a predetermined set refractive index profile becomes a refractive index profile to be estimated(305). If a fixed condition is not satisfied, new refractive index profile is set(306) and the process is returned to the above (303) stage.
