Integrated Weather Radar System for Aviation Hazard Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ground-based weather radar systems have limitations in coverage, including blind spots and inadequate vertical resolution, which can lead to incomplete characterization of weather conditions, particularly over mountainous terrain and oceanic surfaces, posing challenges for aircraft navigation and safety.
Innovation Solution
A multi-source weather radar integrating system that combines data from airborne and ground-based weather radar systems to provide more accurate and higher-resolution weather information, filling gaps in coverage and improving vertical resolution, thereby enhancing the ability to detect convective weather and avoid hazardous conditions.

Engineering Contradiction Analysis
1Area of stationary object
If ground-based weather radar systems are used, then weather detection coverage is provided, but blind spots and inadequate vertical resolution occur
Solution Approach 1:
The patent combines data from multiple sources including ground-based weather radar systems and airborne weather radar systems into an integrated weather information system. This merging of data sources fills blind spots and improves vertical resolution by complementing the limitations of individual systems with the strengths of the other.
Solution Approach 2:
The patent introduces airborne weather radar systems that provide three-dimensional weather data from multiple altitudes and positions, adding a vertical dimension to the traditionally two-dimensional ground-based radar coverage. This enables detection of weather conditions at different flight levels that ground-based systems cannot resolve.
2Loss of information
If ground-based weather radar systems are used, then weather information is provided, but blind spots over mountainous terrain and oceanic surfaces occur
Solution Approach 1:
Instead of relying solely on ground-based systems that radiate outward from fixed locations, the patent inverts the approach by deploying airborne radar systems that move through the coverage gaps. These airborne systems actively seek out and fill blind spots over mountainous terrain and oceanic surfaces by positioning themselves within the problematic areas.
Solution Approach 2:
The system performs preliminary weather detection using available ground-based radar data, identifies blind spots and information gaps, then proactively deploys airborne radar resources to those specific areas before hazardous weather develops or aircraft enter the regions, ensuring continuous coverage.
3Reliability
If aircraft route around two-dimensional convective weather areas, then safety is improved, but unnecessary detours and fuel consumption increase
Solution Approach 1:
The patent uses airborne weather radar data to reveal three-dimensional weather structures, showing that hazardous convective weather is often confined to lower altitudes while upper flight levels remain clear. This vertical dimension information enables aircraft to maintain safe horizontal routing while climbing to higher altitudes, avoiding unnecessary detours and fuel consumption.

AI summary
This disclosure is directed to systems, methods, and devices for integrating weather radar data from both ground-based and aircraft weather radar systems. An example system (100) is configured to receive weather radar data from a first weather radar system (150). The system is further configured to receive weather radar data from one or more additional weather radar systems (170,180). The system is further configured to combine the weather radar data from the first weather radar system and the weather radar data from the one or more additional weather radar systems into a combined weather radar data set. The system is further configured to generate an output based on the combined weather radar data set.
