Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Active sensor systems face challenges in identifying and mitigating sensor conflicts within a sensing zone, particularly when encountering radiation-sensitive areas, which can lead to interference and inaccurate data collection.
Innovation Solution
An active sensing system with a conflict identification module and controller that adjusts the sensing zone by applying limitations to emitters based on location-based radiation sensitivity information, including inhibiting, power, or spectral adjustments to avoid conflicts, while an agent, such as a rotary wing aircraft, scans the area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the active sensor system transmits electromagnetic radiation into the environment to detect objects, then the sensing capability and data collection are improved, but radiation-sensitive areas may be interfered with and sensor conflicts occur
Solution Approach 1:
The system performs preliminary identification of conflict regions containing radiation-sensitive areas before active sensing operations. By预先 establishing geographic information about sensitive areas and predicting potential sensor conflicts, the system can proactively adjust sensing zones to avoid radiation interference while maintaining measurement precision in safe areas.
Solution Approach 2:
The system applies different sensing strategies to different spatial regions. Within conflict regions, the sensing zone is adjusted or restricted to avoid radiation-sensitive areas, while in non-conflict regions, full sensing capability is maintained. This localized adaptation allows the system to preserve measurement precision where possible while avoiding harmful radiation effects in sensitive areas.
2Object-affected harmful factors
If the sensing zone is adjusted to accommodate sensor conflict regions, then radiation interference is avoided, but the area to be sensed is reduced
Solution Approach 1:
The sensing zone is segmented into multiple regions based on conflict identification. The system divides the overall sensing area into conflict regions (where radiation-sensitive areas exist) and non-conflict regions (where normal sensing can proceed). This segmentation allows the system to maintain maximum sensing coverage by continuing to sense in non-conflict areas while only restricting sensing in specific conflict zones, thus minimizing the reduction in total sensing area while still avoiding radiation interference.
3Reliability
If the active sensor controller adjusts the sensing zone by applying limitations to emitters, then sensor conflicts are avoided, but the complexity of the control system increases
Solution Approach 1:
The system introduces a conflict identification module as an intermediary component between the sensor system and the environment. This module serves as a mediator that identifies conflict regions containing radiation-sensitive areas and communicates this information to the active sensor controller. The controller then uses this information to adjust the sensing zone by applying limitations to emitters. This intermediary structure organizes the control logic and makes the system more manageable, reducing the perceived complexity while maintaining high reliability in conflict avoidance.

Function Achieved in This Case
Enables effective scanning of regions of interest by avoiding sensor conflicts, ensuring accurate data collection without encroaching on sensitive areas, thereby enhancing the reliability and precision of active sensing operations.
Implementation Method 1
Active sensors typically transmit electromagnetic radiation into an environment. The electromagnetic radiation reflects off of objects in the environment. Reflected radiation is then measured by the active sensor providing data about the objects.
