| 抄録 | A portable low power FMCW ionosonde has been developed and deployed mainly at unmanned overseas observation points. Due to the low power of transmitting signals, there has been very little interference from existing radio systems around the FMCW ionosondes. The post-observation data processing offers wide possibilities in manipulating the observed data because the FMCW ionosonde records the entire baseband signal and measurement parameters are selected after observation. Output ionograms are equivalent to those of the routine ionosondes operated by the National Institute of Information and Communications Technology. FMCW ionospheric observation technology has been transferred to Kyushu University to aid mainly in Studying the electric field by Doppler observation. |
