Bistatic-radar scattering from medium- to long-wavelength (80 to 200 meters) ocean waves has been observed with the use of loran A (1.85 megahertz) transmissions and a receiver located 280 kilometers away. The received echoes have been converted into a time-delay, Doppler-frequency map in which the effects of anisotropies in the ocean-wave spectra are clearly shown. The distribution of the echoes in delay-Doppler space is consistent with Bragg scattering from trains of dispersed ocean waves.
利用长波（80 至 200 米）海洋波的 loran A（1.85 兆赫）发射和距离 280 公里的接收器，观测到了从中波到长波（80 至 200 米）的双基地雷达散射。接收到的回波已转换为延时多普勒图谱，其中清楚地显示了海洋波谱各向异性的影响。在延迟多普勒空间中，回波的分布与从离散海洋波列的布拉格散射一致。
