| Abstract(in English) | Akebono spacecraft has two pair of dipole antennas as sensors for electric field in the VLF range. To calculate the absolute intensity of observed electric field from an induced voltage at the base of the antenna, we need the effective length of the antenna. However it is not easy to estimate the values of effective lengths in plasmas, and a few researches about it have been made. In these researches, the effective lengths of two dipole antennas have been assumed the same. In this study, we obtain the effective length of each of cross dipole antennas separately by using OMEGA signal. As a result, the effective lengths of two antennas are found to be 30m, which is a half of physical length. |
