摘　　要：继美国1997年发射专用的海洋水色卫星"海星"号(SeaStar)后,2002年5月15日我国成功地发射了专门海洋水色卫星HY-1A.首先概要地介绍了HY-1A卫星的性能和特点;其次运用辐射模拟仿真得到的综合信噪比这一概念从理论上评价了HY-1A卫星资料的利用率,同时利用接收到的HY-1A卫星资料,通过与美国海洋水色卫星资料的比较,评价了测量精度;最后从海洋水色、水温等海洋要素的反演结果讨论了HY-1A卫星资料的应用潜力.研究结果表明,我国的第一颗海洋卫星将在海洋环境监测、海洋资源的管理、保护和开发以及国家权益等方面将有很大的应用潜力,并提出了改进建议.China has launched her first China's ocean clolor satellite HY-1A on May 15,2003 since American ocean color satellite SeaStar was on the orbit in 1997. First, the properties and characteristics of HY-1A are briefly introduced; second, the quality and availability are evaluated by means of the complex signal noise ratio (CSNR) which is simulated theoretically; third, the received HY-1A data are compared with SeaStar data to understand the accuracy of the HY-1A; finally, the remote sensing products of ocean color and temperature are mapped by the (HY-)1A to study its application potentiality. The results show that the HY-1A has its latent capability for the application of marine environment detection, the management and protection of marine resources, and the national rights and interests. Meanwhile some suggestions are proposed to modify the next ocean satellite.
