一台工作频率为47.8兆赫的气象ST雷达已用于海况遥感。发现回波的多普勒频谱的一般特征与在HF处获得的特征相同；然而，当前速度测量的空间分辨率和固有精度可以显著提高。有人提出，如果使用ST雷达的全部功能，在公海上的潜在范围将达到几十公里。实验还表明，在可能的情况下，可以通过提高雷达的高度来扩大探测距离。
A meteorological ST radar operating at a frequency of 47.8 MHz has been used for remote sensing of sea state. General features of the Doppler spectra of the echoes are found to be the same as those obtained at HF; however, space resolution and intrinsic accuracy of the current velocity measurements can be significantly improved. Arguments are presented to suggest a potential range of a few tens of kilometers on the open sea if the full capabilities of ST radars are used. The experiment also shows that, when it is possible, the range could be extended by increasing the altitude of the radar.
