Engineering Contradiction Analysis
1Adaptability or versatility
If joint communication and sensing capabilities are integrated in a single device, then spectrum efficiency and hardware utilization are improved, but testing complexity and measurement accuracy requirements increase
Solution Approach 1:
The testing system is segmented into distinct functional modules: an RF signal generator for creating test signals with controlled characteristics, a JCAS device under test for performing joint communication and sensing operations, and a processor for analyzing detection results. This modular segmentation allows each component to be optimized and tested independently, reducing overall testing complexity while maintaining comprehensive JCAS capability assessment
Solution Approach 2:
The processor acts as an intermediary between the RF signal generator and the JCAS device, coordinating signal transmission, controlling test parameters, and analyzing detection results. This intermediary component simplifies the testing process by centralizing control and analysis functions, thereby reducing testing complexity without compromising the integrated JCAS capability
2Loss of information
If multiple parameters are detected simultaneously (CIR, DOA, Doppler shift, Micro-Doppler shift), then comprehensive device performance assessment is improved, but measurement precision requirements increase
Solution Approach 1:
The system continuously transmits RF signals and continuously analyzes detection results for multiple parameters including CIR, DOA, Doppler shift, and Micro-Doppler shift. This continuous operation allows for comprehensive parameter detection without interrupting the measurement process, ensuring complete information capture while maintaining consistent measurement precision through uninterrupted signal analysis
Solution Approach 2:
The processor analyzes detection results and provides feedback on the accuracy of parameter detection. This feedback mechanism enables continuous optimization of measurement precision by adjusting signal characteristics and analysis parameters based on detected parameter quality, thereby maintaining high precision across all measured parameters simultaneously
