摘要

An empirical relationship between the power of the second-order sea clutter in UF surface wave radar (HFSWR) and the average ocean waveheight is derived from the data measured from a recent trial using the HFSWR at Cape Race, Newfoundland and a TriAxys wave buoy. The power of the second-order sea clutter between Bragg lines, measured at the radio frequency of 3.1 MHz, is found to depend linearly, in logarithmic scale, on average ocean waveheight. Significant ocean waveheight could be used as an indicator for sea state. The linear relationship therefore provides a gauge of the radar performance in ship detection with respect to sea state.
