Abstract

This paper measured entire spectrum in the HF environment of two places by an electromagnetic spectrum monitor system. Based on the above measured data, the HF spectrum characteristics of 2–30 MHz band were analyzed: power spectral density (PSD), Time-frequency distribution, The probability distribution of 3D map, etc. The paper analyzed high frequency bands occupancy one the sea with setting different latitude, season and time as control groups. Hence, we confirm the source of interference noise is broadcasting, and the silent frequency band is obtained. Further analyze has proven it has short-time stationary property. At last, the paper defines the channel availability function for evaluating availability of the channel.
