A new method for recording the parameters of sea waves, based on video recording of the length of vertically located strings, is considered. Cotton strings illuminated by an infrared searchlight glow brightly in their upper part, forming a clear edge at the interface. Measurements can be carried out at any time of the day at distances between the strings from units of millimeters to tens of centimeters. The results of field measurements carried out on an offshore platform are presented. Examples of calculations of elevation spectra, distribution of one-dimensional and two-dimensional slopes, and estimates of anisotropy are presented. The accuracy of measurements, development prospects, and limitations of the proposed method are shown.

考虑了一种记录海浪参数的新方法，该方法基于垂直定位的弦长度的视频记录。被红外线探照灯照亮的棉线在其上部发出明亮的光，在界面处形成清晰的边缘。可以在一天中的任何时间以毫米到数十厘米为单位的弦之间的距离进行测量。介绍了在海上平台上进行的现场测量结果。给出了高程谱计算、一维和二维斜率分布以及各向异性估计的示例。显示了所提出方法的测量精度、发展前景和局限性。
