Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing detection systems use computationally intensive algorithms and complex backend circuits for detecting and tracking target emitters, then the detection accuracy is improved, but the device complexity and testing difficulty increase
Solution Approach 1:
The patent creates a virtual copy of the detection system in software, allowing the complex algorithms and backend circuits to be tested in a simulated environment. This copying approach enables thorough testing of the complex detection system without requiring physical hardware, thereby reducing testing difficulty while maintaining detection accuracy evaluation.
2Reliability
If existing systems perform comprehensive testing of detection systems with complex scenarios, then the reliability of emitter tracking is improved, but the time and cost required for testing increase
Solution Approach 1:
The patent performs preliminary actions by pre-configuring virtual emitters, platforms, and signal propagation models in software before actual testing begins. This preliminary setup allows comprehensive testing scenarios to be executed rapidly without requiring physical hardware assembly, thereby improving tracking reliability assessment while reducing testing time and cost.
Solution Approach 2:
By creating virtual copies of testing scenarios, emitters, and platforms in software, the system enables rapid iteration through multiple testing scenarios without the time and cost constraints of physical hardware testing, while still comprehensively evaluating tracking reliability.
3Ease of operation
If existing systems use fixed and limited testing scenarios, then the ease of operation is improved, but the adaptability to dynamic and realistic flight paths deteriorates
Solution Approach 1:
The patent implements dynamic flight paths by allowing the virtual platform to move along configurable trajectories in the simulated environment. The software enables easy modification of flight paths, emitter positions, and signal characteristics, providing both ease of operation through standardized templates and high adaptability for custom realistic scenarios.
Solution Approach 2:
The virtual testing environment serves multiple functions: it can simulate various flight paths, multiple emitter types, different propagation conditions, and various detection system configurations within a single unified software platform, thereby achieving both ease of operation and high adaptability.
