地球观测卫星通过携带的成像雷达系统,可获得大量的黑白和彩色遥感图像,它们经过图像处理制成专业图像,这些图像可广泛地用于地质、石油、农林、海洋、地震和测绘等多方面的研究.由于地球观测卫星的覆盖面大,可用于大规模的资源普查.卫星的分辨率也在不断提高,Landsat 6的分辨率预计可达5米.目前的星载雷达系统不仅能够反映出大的地质构造,而且能够发现三价铁造成的异常,甚至能够寻找粘土化蚀变.因此它对基础地学研究和矿产勘查具有重要意义.
Earth observation satellites carry a large number of black and white and color remote sensing images through the imaging radar system they carry, which are image-processed to produce professional images that can be used in a wide range of applications including geology, petroleum, agriculture, forestry, oceans, earthquakes and surveying Due to the large coverage of Earth observation satellites, which can be used for large-scale census of resources, satellite resolution is also rising, Landsat 6 resolution is expected to reach 5 meters. The current spaceborne radar system can not only reflect the large Of the geological structure, but also to discover the anomalies caused by ferric iron, and even to find the clay alteration, so it is of great significance for basic geology and mineral exploration.
