摘　　要：随着日益加剧的全球气候变化引发的气象灾害频发和生命财产损失影响的扩大,要求未来的气象卫星观测系统通过自主星上处理、自主任务规划、星间互联互通等智慧观测手段实现快速响应、精准预报、提前预警和连续跟踪。为此,文章以我国第二代静止轨道气象卫星风云四号(FY-4)为例,结合数值天气预报和短临天气预报等业务需求,提出了包括多载荷自主协同观测、定位恒星自主预报、自主太阳规避等智慧观测的设想和实现技术途径,通过气象卫星智慧观测可有效提升卫星应用效能,更好地发挥气象卫星数据服务能力。Caused by increasingly aggravated global climate changing, the frequent occurrence of disasters as well as the impact to life and property call for intelligent observation capacities provided by future meteorological satellites, including fast response, accurate forecasting, early warning and continuous tracking, through autonomous in-orbit processing, autonomous mission planning and inter-satellites interconnection. This paper takes the Chinese second generation geostationary orbit meteorological satellite FY-4 as an example, and proposes visions and technical approach of intelligent observation, considering service requirements such as numerical weather prediction and short-term impending weather forecasting. The requirements including multi-load autonomous collaborative observation, autonomous stellar prediction and autonomous sun-avoid. The capacity of satellite data services will be enhanced through the intelligent observation.
