Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing threat of unmanned aerial vehicles (UAVs) posing risks due to their speed, maneuverability, and ability to carry payloads, which makes them potential weapons for attacks on critical infrastructure, necessitates an effective system for detection and neutralization, especially in large airspaces where existing countermeasures are costly and complex.
Innovation Solution
A system comprising a counter-attack UAV with a flight control system and aerial vehicle detection sensors that detect and intercept target UAVs, using command data to facilitate neutralization through aerial vehicle countermeasures, such as nets or capture devices, supported by ground-based detection systems and on-board sensors for autonomous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If existing countermeasure technologies are used to protect large airspace, then protection coverage is achieved, but cost and system complexity increase significantly
Solution Approach 1:
The protected airspace is divided into multiple zones with different detection and response capabilities. Remote sensors monitor outer zones while closer zones have more sophisticated detection and countermeasure systems, allowing comprehensive coverage without uniformly high complexity throughout the entire airspace.
Solution Approach 2:
A centralized control system acts as an intermediary that receives data from multiple detection sensors, processes threat assessments, and coordinates countermeasure deployment. This mediator approach allows simple sensors to cover large areas while the central system provides the intelligence needed for effective countermeasures.
2Loss of time
If detection and neutralization time is reduced to counter fast-moving drones, then response effectiveness improves, but detection precision and target identification become more difficult
Solution Approach 1:
Multiple detection sensors are positioned to detect and track potential threats at various distances before they reach critical zones. By detecting drones early in their approach and maintaining continuous tracking, the system has advance warning and time to coordinate countermeasures without sacrificing precision through rushed identification.
Solution Approach 2:
The system continuously receives feedback from multiple sensors tracking drone position, speed, and trajectory. This real-time feedback allows the control system to update threat assessments and adjust countermeasure timing, maintaining precision even as response time is compressed by fast-moving targets.
3Reliability
If counter-attack UAVs are deployed to intercept target drones, then neutralization capability is enhanced, but operational cost and system complexity increase
Solution Approach 1:
Counter-attack UAVs are equipped with autonomous navigation and target acquisition systems that allow them to independently intercept and neutralize threats without requiring complex real-time human control or sophisticated coordination systems. Each UAV serves itself by detecting, pursuing, and neutralizing targets autonomously.
Solution Approach 2:
The counter-attack UAVs use simplified copies or models of the target drone characteristics for training and simulation, allowing the system to develop effective neutralization strategies without requiring complex real-world testing. This reduces operational complexity while maintaining neutralization reliability.

AI summary
A system for detecting and neutralizing a target aerial vehicle comprises a counter-attack unmanned aerial vehicle (UAV) comprising a flight body and a flight control system supported about the flight body operable to facilitate flight of the UAV, and an aerial vehicle countermeasure supported by the flight body. The system can comprise an aerial vehicle detection system comprising at least one detection sensor operable to detect a target aerial vehicle while in-flight, and operable to provide command data to the counter-attack UAV to facilitate interception of the target aerial vehicle by the counter-attack UAV. Upon interception of the target aerial vehicle, the counter-attack UAV is operable to disrupt operation of the detected target aerial vehicle with the aerial vehicle capture countermeasure, thereby neutralizing the target aerial vehicle. The counter-attack UAV and systems may be autonomously operated. Associated systems and methods are provided.
