초록
For this study, in order to reduce a measuring error. author used a portable radio mise measuring and processing equipment especially designed. The time & frequency characteristics of HF band radio noise fran the sample site in Yeungnam region had been accomplished and statistical analysis carried out at the site. The results had been compared with the distribution chart of an atmospheric noise :indicated in the CCIR Report 322 issue. It showed that type of a measured noise distribution was similiar to that of the report but the man-made noise had a remarkable effect on the characteristic curves of HF band radio noise about the site.
