Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual acquisition of global map and radar positions is used, then positioning accuracy can be achieved, but time consumption and labor requirements increase significantly
Solution Approach 1:
The system performs automatic coordinate system conversion using detection results from multiple radars to determine relative positions. The radars themselves provide the data needed for conversion, eliminating the need for external manual surveying and mapping operations.
Solution Approach 2:
The patent replaces manual mechanical surveying operations with an automated computational system that processes radar detection data. The coordinate conversion is performed automatically through algorithmic processing of detection results rather than through manual measurement and calculation.
2Measurement precision
If manual acquisition of global map and radar positions is used, then positioning accuracy can be achieved, but labor requirements increase
Solution Approach 1:
The system automatically determines relative radar positions using detection results from the radars themselves. The process requires no external human intervention for coordinate system conversion, as the system self-configures based on mutual detection data between radars.
Solution Approach 2:
The patent uses detection results (virtual representations of object positions) from multiple radars to infer and establish the relative coordinate systems. Instead of copying physical measurement data, the system creates a computational model of radar positions based on detected object coordinates.
3Reliability
If multiple radars are deployed to overcome detection limitations, then positioning reliability improves, but system configuration complexity increases
Solution Approach 1:
The patent merges the coordinate systems of multiple radars into a unified reference frame through automatic conversion. By combining detection results from multiple radars and converting them to a common coordinate system, the system achieves reliable positioning while simplifying the configuration process through automation.
Solution Approach 2:
The patent introduces an automatic coordinate conversion process as an intermediary mechanism between multiple radar systems. This mediator automatically harmonizes the different coordinate systems without requiring manual intervention, thereby managing system complexity while maintaining reliability.

AI summary
A positioning method and a multi-radar positioning system are provided. In the positioning method, a first object and a second object are detected by a first radar to obtain a first coordinate and a second coordinate on a first coordinate system respectively. The first object and the second object are detected by a second radar to obtain a third coordinate and a fourth coordinate on a second coordinate system respectively. A first candidate coordinate and a second candidate coordinate of the second radar on the first coordinate system are estimated according to the third coordinate and the fourth coordinate. The first candidate coordinate is selected from the first candidate coordinate and the second candidate coordinate as a first radar coordinate of the second radar according to the first coordinate and the second coordinate. The first radar coordinate is output.
