种用于将天气雷达回波数据存储至三维缓冲区中的方法和系统。位于飞行器上的该系统(30)包括雷达系统(40)，该雷达系统(40)发射雷达信号和生成雷达测量，该雷达测量作为所发射的雷达信号的雷达回波的结果。三维缓冲区(43)包括多个存储位置。处理器(42)基于所生成的雷达测量、用于存储位置的先前存储的反射率值、和不确定性参数，来生成或更新在三维缓冲区中的存储位置中的反射率值。基于与每个地面元素相关联的地面类型来初始化用于地面元素的归化雷达截面的不确定性参数。基于先验信息来初始化用于天气反射率的不确定性参数。根据存储位置将所生成的反射率值存储在三维缓冲区中。 A method and system for storing weather radar return data into a three-dimensional buffer. The system (30) located on an aircraft includes a radar system (40) that transmits a radar signal and generates a radar measurement as a result of radar return of the transmitted radar signal. A three-dimensional buffer (43) includes a plurality of storage locations. A processor (42) generates or updates a reflectivity value in storage locations in the three-dimensional buffer based on the generated radar measurement, a previously stored reflectivity value for the storage location, and uncertainty parameters. The uncertainty parameters of normalized radar cross section for ground elements are initialized based on a type of ground associated with
