Solution Approach 1:

The simulation system dynamically adapts the level of detail and resolution of simulated targets based on the resolution capabilities of the device under test. The system adjusts simulation parameters in real-time to match the device's resolution, ensuring optimal measurement accuracy without unnecessary computational overhead from fixed high-detail simulations.

Inventive Principle:

Solution Approach 2:

The system changes simulation parameters such as target cross-section size, distance, angular separation, and element complexity based on the device's resolution parameters. By modifying these parameters to align with the device's capabilities, the system achieves both high measurement accuracy and improved efficiency.

Solution Approach 2:

The system performs partial simulation by generating only the necessary level of target detail required for each device's resolution capabilities. Instead of generating complete high-detail simulations for all devices, the system produces appropriately scaled simulations that provide sufficient information without excessive complexity.
