Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If joint communication and sensing capabilities are integrated into a single device, then spectrum efficiency and hardware utilization are improved, but device complexity and testing requirements increase
Solution Approach 1:
The testing system is segmented into separate functional modules: an RF signal generator for creating test signals, a fading module for simulating channel conditions, and a processor for analyzing detection accuracy. This segmentation allows each module to be optimized independently while testing the integrated JCAS device.
Solution Approach 2:
The fading module acts as an intermediary component that simulates real-world channel conditions between the RF signal generator and the JCAS device under test. This intermediary enables realistic testing without requiring actual deployment in complex environments.
2Measurement precision
If comprehensive parameter detection is implemented, then measurement accuracy is improved, but processing complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-configuring the fading module with known channel conditions and pre-generating RF signals with specific characteristics. This allows the processor to focus solely on analyzing detection accuracy without needing to generate test signals or simulate fading conditions during actual measurement.
Solution Approach 2:
The processor compares the detected parameters against known reference values from the generated RF signals and fading conditions, providing feedback on detection accuracy. This feedback mechanism enables precise measurement verification while keeping processing requirements manageable through systematic comparison.
