Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remotely operated aerial vehicles (ROAVs) face challenges in maintaining a consistent radar direction and elevation angle during changes in orientation, which affects their ability to effectively detect and avoid obstacles, especially in dynamic environments.
Innovation Solution
A gimbal stabilized radar system is mounted on a remotely operated aerial vehicle, allowing the radar unit to maintain a constant direction and elevation angle through multiple degrees of freedom, compensating for changes in pitch, roll, and yaw, ensuring continuous and accurate object detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the radar unit is mounted directly on the aerial vehicle without gimbal stabilization, then the device complexity is reduced, but the radar direction and elevation angle cannot be maintained constant during vehicle orientation changes
Solution Approach 1:
The patent applies dynamics by implementing a gimbal system with multiple degrees of freedom that allows the radar unit to dynamically adjust its orientation. The gimbal compensates for vehicle pitch, roll, and yaw movements through active mechanical adjustment, enabling the radar to maintain constant direction and elevation angles despite changes in vehicle orientation during flight operations.
Solution Approach 2:
The gimbal system serves as an intermediary between the aerial vehicle platform and the radar unit. It decouples the radar's directional stability from the vehicle's orientation changes, allowing the radar to maintain a stable viewing direction while the vehicle moves freely. This intermediary mechanism transfers and compensates for orientation disturbances without affecting the radar's measurement precision.
2Reliability
If the radar unit maintains constant direction and elevation angle through gimbal compensation, then obstacle detection accuracy is improved, but the device complexity and weight increase
Solution Approach 1:
The dynamic gimbal system actively compensates for vehicle orientation changes to maintain constant radar direction and elevation angles. This dynamic adjustment ensures reliable obstacle detection accuracy by keeping the radar beam stabilized on target objects even during aggressive maneuvers or turbulent flight conditions.
Solution Approach 2:
The gimbal system provides multi-functionality by simultaneously compensating for multiple orientation parameters (pitch, roll, and yaw) with a single integrated mechanism. This universal approach to stabilization achieves reliable obstacle detection across various flight scenarios without requiring separate compensation systems for each orientation axis.
3Adaptability or versatility
If multiple degrees of freedom are provided in the gimbal system, then compensation for pitch, roll, and yaw changes is improved, but the device complexity increases
Solution Approach 1:
The multi-degree-of-freedom gimbal system provides dynamic compensation for pitch, roll, and yaw orientation changes. Each degree of freedom allows the radar unit to independently adjust for specific orientation disturbances, achieving comprehensive adaptability to various flight conditions while maintaining a manageable mechanical structure through coordinated motion control.
Solution Approach 2:
The gimbal system is segmented into multiple independent rotational axes, each handling specific orientation compensation tasks. This segmentation allows the complex problem of three-dimensional stabilization to be divided into manageable rotational components, where each axis compensates for specific pitch, roll, or yaw movements independently.
