Engineering Contradiction Analysis
1Speed
If traditional weather forecasting systems process microwave link data sequentially, then computational accuracy is maintained, but processing speed and real-time forecasting capability deteriorate
Solution Approach 1:
The patent divides the weather forecasting system into multiple parallel processing pipelines, where each pipeline processes different aspects of microwave link data independently. This segmentation allows simultaneous execution of multiple processing tasks, dramatically improving processing speed while maintaining computational accuracy through distributed computation.
Solution Approach 2:
The system pre-computes transforms and filters for microwave link attributes before actual weather forecasting occurs. By preparing computational components in advance, the system reduces real-time processing complexity and enables faster generation of near real-time weather forecasts without sacrificing accuracy.
2Measurement precision
If the system integrates multiple data sources to improve forecast accuracy, then measurement precision improves, but data processing complexity and computational load increase
Solution Approach 1:
The patent processes data from different sources (terrestrial microwave links, satellite microwave links, weather sensors) through separate processing pipelines before integration. This segmentation allows each data type to be processed with optimized algorithms specific to its characteristics, improving overall forecast accuracy while managing complexity through modular processing.
Solution Approach 2:
The system employs a universal processing framework that handles multiple data types through common parallel processing pipelines. This multi-functional approach integrates diverse data sources (microwave attenuation data, weather sensor readings, satellite information) using unified computational methods, reducing system complexity while maintaining high forecast accuracy.
3Loss of time
If the system processes high-frequency sensor data in real-time, then forecast timeliness improves, but computational resource requirements and processing complexity increase
Solution Approach 1:
The system pre-computes transforms, filters, and lookup tables for microwave link attributes before they are needed for forecasting. This preliminary preparation significantly reduces the computational power required during real-time processing, enabling the system to handle high-frequency sensor data with low latency without requiring excessive computational resources.
Solution Approach 2:
By dividing real-time data processing into multiple parallel pipelines that handle different data streams and computational tasks simultaneously, the system distributes computational power requirements across multiple processing units. This segmentation enables efficient utilization of available computational resources while maintaining low forecast latency.
4Measurement precision
If the system uses complex algorithms to distinguish fog from other atmospheric interference, then measurement precision improves, but processing time and computational complexity increase
Solution Approach 1:
The system pre-computes characteristic signatures and filters for different atmospheric conditions (fog, rain, snow, humidity) based on microwave link attenuation patterns. These pre-computed reference data enable rapid comparison and identification during real-time processing, improving atmospheric condition identification accuracy without requiring complex real-time computations.
Solution Approach 2:
The patent implements separate processing pipelines for analyzing different atmospheric conditions, each optimized for specific weather phenomena. This segmentation allows the system to apply specialized algorithms for distinguishing fog from other interference types in parallel, improving identification accuracy while maintaining processing speed through distributed computation.
