低周波パルスサウンダーによる下部電離層観測の基礎実験
In order to obtain basic data on the lower ionosphere in the Antarctic region, the usual ionosonde was remodeled into a portable type of low-frequency pulse sounder equipped with all solid state circuits except the final stages, which was suitable to field experiment. Three experiments were carried...
