Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data communication systems in airports face limitations in bandwidth, coverage, and reliability, especially during emergencies or at busy airports, due to the reliance on voice communication and other high-speed links which are often overwhelmed by the demand for real-time weather and situational awareness data.
Innovation Solution
Utilizing existing X-band weather radar systems on aircraft as a high-bandwidth radio communication device to broadcast and receive digital data, including weather and situational awareness information, thereby reducing the load on other communication channels and enhancing data transfer capabilities without requiring additional hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If voice communication channels are used for weather and situational awareness data, then communication infrastructure is simple, but bandwidth is limited and channels become overwhelmed at busy airports
Solution Approach 1:
The patent makes the weather radar system perform multiple functions: its primary weather detection function plus a secondary data communication function. The radar transmits weather data and receives situational awareness data through the same X-band communication channel used for weather scanning, eliminating the need for separate dedicated communication infrastructure.
Solution Approach 2:
The weather radar system uses its own transmitted signals as the communication medium. By embedding data within the radar's own transmission cycle and using its receiver to capture returning signals, the system serves its own communication needs without requiring external communication infrastructure.
2Productivity
If broadband and satellite communication links are used, then data communication bandwidth is sufficient, but coverage area is limited and links are periodically unavailable
Solution Approach 1:
The patent replaces complex mechanical communication infrastructure (broadband towers, satellite dishes) with an electromagnetic field-based solution using existing radar waves. This substitution provides more reliable coverage in remote areas where physical communication infrastructure is absent or prone to failure.
3Productivity
If separate communication equipment is added for data exchange, then data communication capability is enhanced, but system complexity and cost increase
Solution Approach 1:
The radar system is modified to perform both weather detection and data communication functions using the same hardware components. The transmitter, receiver, and antenna serve dual purposes, eliminating the need for separate communication equipment and reducing overall system complexity.
Solution Approach 2:
The patent merges the weather radar function with the data communication function into a single integrated system. By combining these functions, the patent reduces the number of separate systems needed while maintaining both capabilities.

AI summary
This disclosure is directed to weather radar (40A,B) configured to act as a communication device to allow real time data communication. This disclosure describes using weather radar on board aircraft as a high bandwidth X-band radio for communication. The X-band weather radar is used for receiving flight related data and weather-related data while still acting as a weather radar. As the weather radar system is already present on most commercial aircraft, there is no requirement for additional hardware, devices or equipment onboard the aircraft to meet the data communication needs. An airport may install an X-band data transmitter to broadcast digital data received from detection systems at or near an airport such as an Automated Weather Observing System (AWOS), predictive wind shear (PWS) and bird strike warning systems.
