A method, system, and computer program product for storing weather radar return data into a three-dimensional buffer. The system located on an aircraft includes a radar system 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 includes a plurality of storage locations. A processor 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 each of the elements. The uncertainty parameters for weather reflectivity are initialized based on a priori information. The generated reflectivity values are stored in the three-dimensional buffer according to the storage locations. |
