Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple radar units are arranged to provide 360-degree field-of-view, then detection coverage is improved, but device complexity increases
Solution Approach 1:
The radar system is divided into multiple independent radar units (first radar unit, second radar unit, etc.), each responsible for a specific field-of-view sector. These segmented units collectively provide 360-degree coverage while maintaining individual unit simplicity, resolving the contradiction between comprehensive detection and system complexity.
Solution Approach 2:
Multiple radar units are synchronized to operate together as a unified system. The radar synchronizing controller coordinates the operation of separate radar units to function as a single integrated system, achieving 360-degree coverage without proportionally increasing operational complexity.
2Measurement precision
If radar units are synchronized to operate as single virtual radar unit, then measurement precision is improved, but device complexity increases
Solution Approach 1:
A radar synchronizing controller serves as an intermediary device that manages the coordination between multiple radar units. This dedicated synchronization controller handles the complexity of coordinating multiple units, enabling precise velocity and location measurements while isolating the complexity from the radar units themselves.
3Area of stationary object
If radar units are arranged in ring-like pattern, then field-of-view coverage is improved, but manufacturing complexity increases
Solution Approach 1:
The radar system uses multiple discrete radar units that can be independently manufactured and then assembled in a ring-like pattern. This segmentation allows each unit to be produced using standard manufacturing processes, while the modular design simplifies the assembly process compared to creating a single complex 360-degree radar unit.

AI summary
A plurality of radar units is included in an overall radar module such that the plurality of radar units effectively cooperates to provide an approximately 360-degree field-of-view over a relatively long range. The overall radar module may include a ring-shaped printed circuit board, and a rim that includes multiple radar units positioned to substantially cover a 360-degree field-of-view. Radar units of the overall radar module may be grouped together such that two or more radar units may operate substantially synchronously, e.g., as a substantially single radar unit.
