Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a RADAR system is simulated using a computer model, then development time and cost are reduced, but the accuracy and reliability of the simulation may be compromised
Solution Approach 1:
The patent creates a virtual copy of the RADAR system through a computer model that replicates the transmit chain, receive chain, and data processing chain. This digital twin allows comprehensive simulation of RADAR operations without physical prototypes, significantly reducing development time while maintaining reliability through validated simulation algorithms and comparison with actual system data.
Solution Approach 2:
The simulation model is developed and validated before the actual RADAR system is fully built or deployed. By performing preliminary simulations, designers can optimize system parameters, identify potential issues, and validate concepts early in the development process, reducing overall development time while ensuring the final system meets performance requirements.
2Reliability
If comprehensive validation is performed by comparing simulated outputs with actual outputs, then model reliability is improved, but the time and computational resources required increase
Solution Approach 1:
The validation process uses feedback by comparing simulation outputs with actual RADAR system outputs and iteratively adjusting the simulation model parameters. This feedback loop ensures high model reliability by continuously improving the accuracy of the virtual model, while the automated nature of the comparison reduces the manual time required for validation.
Solution Approach 2:
The validation process is designed to be semi-automated, where the simulation system itself performs the comparison with actual outputs and generates validation results. This self-service approach reduces the need for extensive manual testing and validation time, as the system automatically identifies discrepancies and suggests corrections.
