| 抄録 | We have developed a new automatic scaling software of ionospheric parameters. Automatic monitonrig of ionospheric irregularities has become more important since the ionospheric irregularities cause severe disturbances for recent sophisticated communication and navigation systems. NICT carries out a project to monitor the ionosphere in South-East Asia for early warning of occurrences of ionospheric irregularities. In this project, developing the automatic scaling software of ionogram occupies one of the important parts. In this paper, we report the new automatic scaling software of ionospheric parameters in detail. This software consists of noise reduction by wavelet transform and 2-D low-pass filter, detection of E/F-region echo traces, reduction of E/F-region multi-echoes and logical error omitting filter. We demonstrate its higher performance than old one by comparing automatically and manually scaled ionospheric parameters. |
