Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If radar sensor units are integrated into the missile tip, then target acquisition accuracy is improved, but the missile tip functionalization is limited
Solution Approach 1:
The radar sensor unit is segmented from the missile tip structure, with the antenna mounted on the missile body surface rather than integrated into the tip. This allows the missile tip to be functionalized independently for other purposes while the radar sensor performs target acquisition on the missile body.
Solution Approach 2:
The radar antenna is mounted on the circumferential surface of the missile body, utilizing the lateral dimension rather than the longitudinal tip area. This spatial repositioning resolves the conflict between tip functionalization needs and radar sensor integration.
2Measurement precision
If complex radar sensor units are used to improve target detection accuracy, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The strip-shaped radar antenna serves multiple functions: target acquisition, target detection, and field of view alignment. This multi-functionality reduces the need for separate specialized components, thereby simplifying the overall radar sensor unit implementation while maintaining detection accuracy.
Solution Approach 2:
The invention uses a strip-shaped antenna geometry with specific dimensional parameters (length significantly greater than width) to achieve enhanced target detection accuracy through improved radar cross-section and directional characteristics, avoiding the need for more complex sensor architectures.
