Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physical radars are used for tracking performance evaluation, then measurement precision is improved, but device complexity and operational burden increase
Solution Approach 1:
The patent creates a virtual copy of the physical radar system through software simulation. The radar simulation module generates synthetic radar measurements that replicate the statistical characteristics and performance parameters of actual radar systems, allowing evaluation without requiring the physical radar hardware to be present at the test site.
Solution Approach 2:
The patent introduces an intermediary simulation layer between the target and the evaluation system. Instead of directly measuring with physical radar, the system uses a radar simulator that receives target position data and generates intermediate radar measurement data, which is then used for performance evaluation.
2Reliability
If physical radars are deployed for performance testing, then reliability of measurements is improved, but ease of operation deteriorates due to setup and operational burden
Solution Approach 1:
The system replaces the need to operate physical radar equipment with a software-based radar simulator that replicates radar measurement behavior. This copying approach maintains measurement reliability through statistical modeling while dramatically simplifying operation, as the simulation can be configured and executed without specialized radar operators or complex hardware setup.
3Adaptability or versatility
If multiple physical radars are used for comprehensive evaluation, then adaptability of testing scenarios is improved, but loss of substance increases due to operational costs
Solution Approach 1:
The radar simulation system is designed to be universal, capable of modeling multiple different radar types and configurations through software configuration rather than requiring separate physical radar systems. The simulation can adapt to various radar waveforms, frequencies, and performance characteristics, providing multi-functional evaluation capability without additional hardware costs.
Solution Approach 2:
Instead of acquiring and operating multiple expensive physical radar systems, the patent creates virtual copies of different radar types through software simulation. This allows comprehensive evaluation across multiple radar configurations while eliminating the substantial costs associated with acquiring, maintaining, and operating multiple physical radar systems.
4Measurement precision
If physical radar systems are acquired for evaluation, then measurement precision is improved, but ease of manufacture deteriorates due to acquisition burden
Solution Approach 1:
The patent replaces the complex process of acquiring, installing, and configuring physical radar systems with a software-based simulation approach. The radar simulation module can be deployed as software without the need to manufacture or acquire expensive radar hardware, dramatically simplifying the acquisition process while maintaining measurement precision through accurate statistical modeling of radar performance characteristics.

AI summary
A computer-implemented radar simulation method is provided for directing a radar beam to a target. The method includes receiving target position from the target; computing target coordinates in a select frame of reference; inserting random noise error into the target coordinates as accuracy degradation to represent at least one radar performance characteristic; providing the accuracy degradation into the frame of reference; and directing the radar beam by the accuracy degradation towards the target.
