Analysis of Radio Environments Allocated to HF Ocean Surface Radar in Korea

Abstract

Partial high frequency bands were allocated to the operation of ocean surface radars that monitor the sea surface currents and waves in WRC-12. On that basis, government-related organizations revised the table of domestic frequency allocation. In order to study radio environments in the allocated bands for ocean radar, tests of the radio signal spectrum were carried at 7-sites using the receiver of the ocean surface radar system operated with a shutdown of the transmitter for 10−60 min. The results showed that no serious radio noises occur at 25 and 43 ㎒ bands, indicating a good radio environment for the ocean surface radar operation. However, at 13 ㎒ band, it was difficult to generate stable and confidential data from the ocean surface radar because serious radio noises occurred continuously.
