双站雷达布拉格散射的中长波长无线电波的海浪，可以用来作为一种手段，观察定向海浪频谱。只需要适度的天线方向性;区域和方向分辨率由雷达回波的高分辨率延迟多普勒处理提供。使用LORAN A发射（1.85 MHz）和距离发射器280公里的接收器观测了长波（80-200米）海浪的方向特性。接收到的信号已被转换成一个时间延迟多普勒频率图和归一化雷达截面积？0，作为方向海洋波数的函数。
Bistatic-radar Bragg scattering of medium-to long-wavelength radio waves by ocean waves can be used as a means for observing directional ocean-wave spectra. Only moderate antenna directivity is required; areal and directional resolution are provided by high-resolution delay-Doppler processing of the radar echoes. Directional characteristics of long-wavelength (80-200 m) ocean waves have been observed using LORAN A transmission (1.85 MHz) and a receiver located 280 km from the transmitter. The received signals have been converted into a time-delay Doppler-frequency map and into a plot of normalized radar cross section ?0, as a function of directional ocean-wavenumber.
