Solution Overview
Problem
Existing weather radar systems face challenges in efficiently transmitting three-dimensional weather data to base receivers due to resource constraints, necessitating a more balanced approach between data accuracy and transmission volume.
Innovation Solution
The system compresses three-dimensional weather data into a plurality of two-dimensional representations, selecting and transmitting a subset based on reflectivity data severity to reduce transmission volume while maintaining accuracy.

Engineering Contradiction Analysis
1Measurement precision
If three-dimensional weather radar data is transmitted in full resolution, then data accuracy is improved, but transmission volume and resource consumption increase
Solution Approach 1:
The three-dimensional weather radar data is segmented into multiple two-dimensional representations (such as range-azimuth planes at different elevation angles). This segmentation allows selective transmission of only the most relevant 2D slices, reducing overall data volume while preserving critical weather information for analysis
Solution Approach 2:
The system extracts and transmits only the most significant two-dimensional representations from the three-dimensional data set. By identifying and transmitting only the essential weather patterns and features in 2D format, the system reduces transmission volume while maintaining the accuracy needed for weather analysis and flight decision-making
2Quantity of substance
If three-dimensional weather radar data is compressed into two-dimensional representations, then transmission volume is reduced, but data complexity increases
Solution Approach 1:
The system transforms three-dimensional weather radar data into multiple two-dimensional representations by projecting the 3D data onto 2D planes at different orientations and positions. This dimensionality reduction simplifies the data structure for transmission while the plurality of 2D representations collectively preserves the essential three-dimensional weather information needed for accurate analysis

AI summary
A method of processing weather data is described that includes receiving, in a vehicle and from a detection system, reflectivity data sampled for a three-dimensional volume of space. The method further includes generating, based on the reflectivity data, a plurality of two-dimensional representations of the reflectivity data. The method further includes transmitting, by a transmission device to a base receiver, a subset of the plurality of two-dimensional representations, wherein each two-dimensional representation of the subset of the plurality of two-dimensional representations comprises a plurality of data points.
