Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing population of drones and other aircraft in airspace poses a risk of conflicted airspace, as existing radar technology cannot detect all aircraft, leading to potential disruptions, damages, or injuries due to the lack of monitoring and tracking by regulatory agencies.
Innovation Solution
A multi-channel remote identification system that uses various detection channels such as wireless networks, visual, acoustic, and radar to identify and track aircraft, supplementing traditional radar systems by forming a distributed set of devices and sensors to provide comprehensive airspace monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional radar technology is used for aircraft detection, then detection capability for conventional aircraft is maintained, but detection capability for drones and small aircraft is insufficient
Solution Approach 1:
The system segments the detection task into multiple specialized detection channels (radar, acoustic, visual, wireless) rather than relying on a single radar system. Each channel is optimized for specific types of aircraft, with acoustic and visual channels particularly effective for drones and small aircraft that radar cannot detect.
Solution Approach 2:
The system creates a multi-functional detection network that can identify various types of aircraft (conventional aircraft, drones, small aircraft) using multiple detection methods. The distributed sensors and devices perform multiple functions including detection, identification, and tracking across different frequency and sensing modalities.
2Reliability
If multiple detection channels are used to identify aircraft, then comprehensive airspace monitoring is achieved, but system complexity increases
Solution Approach 1:
The system merges data from multiple independent detection channels (radar, acoustic, visual, wireless) into a unified aircraft identification and tracking system. By combining these channels, the system achieves comprehensive monitoring while managing complexity through integrated data processing and correlation algorithms.
Solution Approach 2:
The system introduces intermediary processing layers that correlate data across different detection channels. These intermediaries match identifying information from multiple channels to confirm aircraft identity, reducing false positives and managing the complexity of multi-channel data integration.
3Area of stationary object
If distributed sensors and devices are deployed for multi-channel detection, then detection coverage is improved, but system cost and deployment difficulty increase
Solution Approach 1:
The system employs self-service principles by utilizing existing commercial off-the-shelf sensors and devices (acoustic sensors, cameras, wireless communication equipment) that can be deployed by local authorities or organizations without requiring specialized manufacturing or complex installation procedures.

Data Source
AI summary
An aircraft detection system supplements the identification of aircraft with information that is obtained from two or more different detection channels. The system may obtain a first set of identifying information about a particular aircraft or flight via a first detection channel at a first time, may determine that the first set of identifying information lacks commonality with previously received sets of identifying information for other detected aircraft of flights, and may track the particular aircraft or flight based on the first set of identifying information. The system may then obtain a second set of identifying information via a different second detection channel at a second time, may determine commonality between the second set of identifying information and the first set of identifying information, and may update the tracking of the particular aircraft or flight by incorporating or adding identifying information from the second set of identifying information.
