Abstract
In support of the operation of the east coast High Frequency Surface Wave Radar (HFSWR) systems, we carried out a continuous measurement of noise and interference data in the frequency band of 3-6 MHz at Cape Race, Newfoundland in the period between August 1, 1998 and May 10, 2000. In [3], we presented an estimation of noise factors from the measured data. In this report, we study the channel availability, in terms of channel width and channel duration, by using the measured data. The aim of this study is to find the clear channels in which we can effectively operate the radar. The results of the study indicate: (1) channels with a bandwidth of 20 kHz are readily available, and (2) the number of available and non-overlapped channels decreases quickly as channel bandwidth increases. At a bandwidth of 100 kHz, there is no channel available.
