七十年代里,美国航宇局发射了三颗“陆地卫星”,证明了空间遥感是勘测和管理地球资源的极为有效手段。同时,该局又发射了一颗“海洋卫星”。通过这两种不同的遥感卫星,对整个地球的陆地和海洋有可能进行全面的观测,尤其是在“海洋卫星”上采用了微波遥感技术,使空间遥感发生革命性的进步。此外,美航宇局还发射了气象和环境监视卫星,诸如雨云与泰罗斯-N、热测绘、地磁观测以及
In the 1970s, NASA launched three “land satellites”, proving that space remote sensing is an extremely effective means of surveying and managing the earth’s resources. At the same time, the agency launched another “ocean satellite.” Through these two different types of remote sensing satellites, it is possible to conduct a comprehensive observation of the entire terrestrial and oceans of the Earth. In particular, the use of microwave remote sensing technology in “ocean satellites” has revolutionized space remote sensing. In addition, the United States Aerospace Agency also launched meteorological and environmental surveillance satellites, such as Nimbus and Tyros-N, thermal mapping, geomagnetic observations and
