摘要
针对定量遥感这一广泛应用于气象、海洋与环境等领域卫星的遥感技术,分析了各个领域的应用需求。为了解决如何根据定量遥感的应用需求,快速配置有效载荷,并合理设置有效载荷的探测谱段(频段)这一制约卫星发展的关键问题。提出了从探测目标着手的方法,首先,分析满足探测要素所需的谱段设置、指标要求和有效载荷配置类型,得出了有效配置载荷的方法和思路;其次,以全球云探测为例,验证本方法的合理性;最后,分析定量遥感有效载荷的发展重点和发展方向,为气象、海洋与环境领域等定量遥感卫星的长期发展提供技术支撑。
The application requirements of quantitative remote sensing in various fields such as meteorology,ocean,and environment are analyzed. In order to solve the key problem of how to quickly allocate the payload and reasonably set the detection spectrum(frequency band) of the payload according to the application requirements of quantitative remote sensing,this paper proposes a method starting from the detection target. First,the spectrum setting,index requirements,and payload allocation type required by the detection elements are analyzed. Then,the global cloud detection is taken as an example to verify the rationality of the proposed method. Finally,the development focus and direction of quantitative remote sensing payload are analyzed,which can provide technical support for the longterm development of quantitative remote sensing satellites in the fields such as meteorology,ocean,and environment.
