Aircraft Meteorological Radar Meshing for Extended Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing meteorological radars on aircraft have limited detection distance and area due to softening and reflection of electromagnetic waves by air and clouds, reducing the accuracy and extent of meteorological condition determination.
Innovation Solution
A process and device that utilize a space meshing system to combine primary meteorological information from the aircraft's radar with auxiliary information from external sources, such as neighboring aircraft or ground stations, to determine extended meteorological conditions, enhancing the detection area and providing pilots with a broader understanding of surrounding weather conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If meteorological radar emits electromagnetic waves to detect weather conditions, then meteorological information can be obtained, but the detection distance is reduced due to softening and reflection of waves by air and clouds
Solution Approach 1:
The patent combines primary meteorological information from the aircraft's own radar with auxiliary meteorological information from external sources (other aircraft, ground stations) to create a comprehensive view of weather conditions in an extended geographical area, thereby compensating for the limited detection distance of a single radar system
Solution Approach 2:
The patent introduces a meshing system as an intermediary structure that integrates data from multiple sources. This meshing acts as a mediator that combines primary and auxiliary meteorological information to extend the effective detection area beyond what a single radar can achieve
2Area of stationary object
If radar detection area is limited by electromagnetic wave properties, then device complexity remains simple, but the area of geographical coverage is reduced
Solution Approach 1:
The patent makes the meteorological information system multi-functional by enabling it to receive and process not only primary radar data from the own aircraft but also auxiliary information from external sources, thereby extending the detection area without proportionally increasing device complexity
Solution Approach 2:
The patent divides the extended geographical area into a meshing structure with multiple points, allowing systematic integration of meteorological information from various sources. This segmentation enables manageable processing of data from multiple external sources while expanding the overall detection coverage

Function Achieved in This Case
This approach allows for a wider detection area, enabling pilots to better adapt flight trajectories and avoid hazardous conditions, thereby improving safety and comfort by providing comprehensive meteorological data beyond the limitations of a single radar's range.
Implementation Method 1
meteorological radars emit electromagnetic waves in a given direction and analyze return waves sent back by targets (droplets, hails, etc.)
Implementation Method 2
reflecting the latter on obstacles (for instance, mountains)
Implementation Method 3
softening electromagnetic waves, more specifically by the air and clouds
