引言海洋占全球面积近75%,它与人类的生存密切相关,人类认识海洋的活动,早在古代就已经开始了。但是,由于条件的限制,对海洋的调查一向采用由陆地或由调查船进行观测的方法。因此,人们对海洋的研究,也就被局限在浩瀚海洋的狭小范围里。近些年来,由于利用卫星的新测量技术的发展,特别是随着地球资源技术卫星的成功,显示了提供大范围海洋情报的可能性。遥感技术在海洋上的应用,将改变海洋调查的面貌,
Introduction Marine accounts for nearly 75% of the global area. It is closely related to the survival of mankind. Mankind’s knowledge of the ocean has already started in ancient times. However, due to the limitations of conditions, the survey of oceans and seas has always adopted a method of observation by land or by survey vessels. Therefore, people’s study of the oceans and seas has also been confined to the narrow limits of vast oceans. Recent years have seen the possibility of providing a wide range of oceanographic intelligence due to the development of new measurement technologies that utilize satellites, especially with the success of the Earth Resources Technology Satellite. The application of remote sensing technology in the oceans will change the face of marine surveys,
