摘要海洋表面流雷达（OSCR）高频雷达测量的海浪和海流在1999年秋季的浅水波实验（SHOWEX）。在某些时期，在某些位置，获得了高质量的波浪测量结果。由于OSCR硬件，部署配置，信噪比和天线旁瓣的波测量能力的限制进行了识别和讨论。在天线方向图失真的存在下，短时间的大电流被确定为在波测量中的主要误差的来源。
Abstract Ocean Surface Current Radar (OSCR) HF radar measurements of ocean waves and currents were made during the Shoaling Waves Experiment (SHOWEX) in the fall of 1999. During some periods, at some locations, good quality wave measurements were obtained. Limitations in the wave measurement capability due to OSCR hardware, deployment configuration, signal-to-noise ratio, and antenna sidelobes are identified and discussed. A short period of large currents in the presence of antenna pattern distortion is identified as the source of the main errors in the wave measurements.
