利用人造卫星遥感某些海洋要素是从六十年代的气象卫星开始的,气象卫星的实践证实了利用遥感技术观测海洋的可能性。因此,到七十年代,有人提出海洋卫星的设想,这就是发射专用的海洋卫星观测占地球表面积百分之七十一的海洋,如大洋上的风、浪、流、海面温度、盐度、石油污染、水色、海冰等。美国预计在今年发射海洋卫星“Sea-Sat-A,标志着遥感技术进入一个新阶段。这里,回顾一下遥感技术的发展进程,将有助于我们认识这个新阶段对海洋调查和海洋科研的意义。
The use of satellites for remote sensing of certain ocean elements started with meteorological satellites in the 1960s and the practice of meteorological satellites confirmed the possibility of using remote sensing to observe the oceans. Therefore, by the 1970s, the idea of a marine satellite was proposed. That is, a dedicated oceanographic satellite (SSO) observes oceans accounting for 71% of the surface area of the Earth. For example, oceanic winds, waves, currents, sea surface temperatures, salinity, Oil pollution, water color, sea ice and so on. The United States is expected to launch this year’s satellite “Sea-Sat-A”, marking a new phase in remote sensing technology. Here, reviewing the development of remote sensing technology will help us understand the significance of this new phase for marine investigation and marine scientific research. .
