  Abstract

The refractive index of the atmosphere curves the path of long-range radar signals, causing errors in estimating the distance and position of targets. If the atmospheric refractive index is known, it is possible to compensate for target estimation errors. However, in cases where this information is unavailable, the target position is estimated based on the ITU global mean atmospheric refractive index. This can introduce errors compared to the actual position. In this paper, the author utilized information from co-operative target known in advance to model the path of beam, enabling real-time estimation of the atmospheric refractive index. The proposed algorithm was validated by comparing it with previous atmospheric refractive index model and actual measurement data from radiosonde.
