Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple radar systems operate in the same frequency band, then frequency utilization is improved, but signal interference increases
Solution Approach 1:
The patent segments the frequency band by assigning different identification codes to different radar systems. Each radar system transmits signals with its unique identification code, allowing multiple systems to operate simultaneously in the same frequency band without causing harmful interference to each other.
Solution Approach 2:
The patent changes the phase parameter of transmission signals based on identification codes. By adjusting the phase of transmitted signals according to specific identification codes, the system enables multiple radar systems to coexist in the same frequency band while maintaining signal distinguishability and minimizing interference.
2Measurement precision
If phase adjustment is applied to transmission signals, then signal distinction accuracy is improved, but device complexity increases
Solution Approach 1:
The patent adjusts the phase parameter of transmission signals according to identification codes. This parameter change enables the receiver to distinguish between signals from different radar systems, improving signal distinction accuracy while maintaining a relatively simple system architecture.
