这是一篇在IEEE Oceans 2016上发表的论文的更新，发表在IEEE Xplore：2016年12月1日（ISBN：978-1-5090-1537-5）。FutureWaves™波浪和船舶运动预报系统自2016年在加州蒙特雷举行的海洋大会上推出以来，已经取得了长足的发展。该系统的美国海军变体已经过渡到用户操作评估系统，并且商业变体最近在北海的大型半潜式起重机船上进行了为期六个月的活动期间进行了广泛的评估。美国航天局还将该系统添加到其设备包中，用于在海上回收新的ORION航天器。该系统提供了一种独特的能力，可以对未来几分钟内的入射波和由此产生的船舶运动进行计时。这是通过创新的波浪传感技术来实现的，该技术在没有波浪浮标的情况下提供详细的海面分析。虽然现场海浪测量的黄金标准仪器是惯性浮标，但后勤（即部署、监测、回收等）使替代遥感方法具有吸引力。X波段海洋雷达就是这样一种方法，它解决了浮标的后勤挑战。然而，大多数商业上可用的波感测雷达系统处理反射功率以分析海浪。该方法需要使用基于远程测量位置处的风强度的传递函数，该传递函数只能近似。FutureWaves系统使用专门为海浪传感定制的X波段雷达，通过使用专门的接收电子设备和垂直极化天线提供海洋表面速度的多普勒测量。测量的海洋表面速度是对海浪的直接测量，消除了容易出错的传递函数。处理这些高保真度的海洋表面的现场测量提供统计波信息（高度，周期和方向），方向波功率谱，并重建相位分辨波场，允许波定时和船舶运动预报。在这篇综述中，我们介绍了2018年春季和夏季进行的北海测试的系统细节和结果，海高高达5米。部署的系统包括波浪计时能力和基于RAO的船舶模型，用于提前90秒提供精确的船舶运动预测。
This is an update to a paper presented at IEEE Oceans 2016 and published in IEEE Xplore: 01 December 2016 (ISBN: 978-1-5090-1537-5). The FutureWaves™ Wave and Vessel Motion Forecasting System has evolved considerably since its introduction at Oceans 2016 in Monterey, California. The US Navy variant of the system has undergone transition to a user operational evaluation system, and the commercial variant recently underwent extensive assessment during a six month campaign in the North Sea aboard a large semi-submersible crane vessel. NASA has also added the system to its equipment package for at-sea recovery of the new ORION spacecraft. The system provides a unique capability to time incident waves and resultant vessel motions for minutes into the future. This is accomplished by an innovative wave sensing technique that provides detailed ocean surface analysis without a wave buoy. While the gold standard instrument for in-situ ocean-wave measurement is inertial buoys, logistics (i.e. deployment, monitoring, recovery, etc.) make alternative remote sensing methods attractive. X-band marine-radar is one such method that alleviates the logistical challenges of a buoy. However, most commercially available wave-sensing radar systems process reflected power to analyze the ocean waves. This method requires the use of a transfer function based on wind strength at the remote measurement location, which can only be approximated. The FutureWaves system uses an X-band radar specifically customized for ocean wave sensing, providing a Doppler measurement of the ocean surface velocities by using specialized receive electronics and a vertically polarized antenna. The measured ocean surface velocities are a direct measure of the ocean waves, eliminating the error-prone transfer function. Processing with these high-fidelity field measurements of the ocean surface provides statistical wave information (height, period, and direction), a directional wave power spectrum, and a reconstruction of the phase-resolved wave field that allows wave timing and ship motion forecasting. In this review we present system details and results from the recent North Sea test conducted over the spring and summer of 2018 with sea heights up to 5 meters. The system as deployed included the wave timing capability and RAO based models of the vessel that were used to provide precise vessel motion predictions up to 90 seconds in advance.
