Airspace Collision Avoidance Interface for UAVs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned aerial vehicles (UAVs) operating in crowded airspace, such as over cities, face challenges in avoiding collisions with various obstacles due to the lack of sufficient information about their environment, including other aircraft, balloons, buildings, and structures, which existing systems fail to address effectively.
Innovation Solution
A system that receives and analyzes 3-D radar scan data to determine collision avoidance information, including locations of airborne objects, and transmits specific instructions to UAVs to facilitate safe operation, using a radar system communication interface and an aerial vehicle communication interface to provide real-time collision avoidance data to associated UAVs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 3-D radar scans are used to detect airborne objects, then collision avoidance information is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary processing system that receives raw radar scan data, analyzes it to determine collision avoidance information, and transmits processed results to aerial vehicles. This intermediary layer simplifies the overall system architecture by separating radar detection from collision avoidance processing, allowing each component to be optimized independently while maintaining high reliability.
2Reliability
If real-time collision avoidance data is transmitted to UAVs, then safety is improved, but loss of time in data processing increases
Solution Approach 1:
The system performs preliminary analysis of radar scan data to pre-determine collision avoidance information before transmitting it to aerial vehicles. By preparing collision avoidance data in advance based on radar detections, the system reduces real-time processing delays and ensures safety-critical information is available when needed without excessive latency.
Solution Approach 2:
The patent implements a feedback mechanism where collision avoidance information is continuously updated and re-transmitted to aerial vehicles based on changing airspace conditions. This closed-loop feedback ensures that safety information remains current and accurate, allowing UAVs to adjust their flight paths in real-time while maintaining efficient data processing through iterative updates rather than continuous re-analysis.

Data Source
AI summary
A process is described that includes the generation and transmission of collision avoidance data and/or collision avoidance instructions based on data from 3-D radar scans of an airspace. The transmitted data and/or instructions could facilitate collision avoidance by aerial vehicles operating in the airspace. The transmitted data could be limited to protect the security, privacy, and/or safety of other aerial vehicles, airborne objects, and/or individuals within the airspace. The transmitted data could be limited such that only information pertaining to a region of the airspace proximate to a particular aerial vehicle was transmitted. The transmitted data could be limited such that it included instructions that could be executed by a particular aerial vehicle to avoid collisions and such that the transmitted data did not include location or other data associated with other aerial vehicles or airborne objects in the airspace.
