Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If SAR data is re-processed at a remote data center to generate alternative images with different parameters, then image processing flexibility is improved, but processing time and data transfer requirements increase
Solution Approach 1:
The system segments the SAR processing workflow by separating the computationally intensive re-processing operations from the interactive exploration operations. Raw SAR data is transferred to a remote data center for initial processing into intermediate products, which are then transferred back to a local workstation for rapid iterative processing with different parameters. This segmentation allows flexibility to be maintained through remote re-processing while minimizing time losses by performing only necessary operations locally.
Solution Approach 2:
The system performs preliminary processing actions by pre-computing intermediate SAR products from raw data at the remote data center before the analyst needs to explore different parameter settings. These pre-processed intermediate products are stored locally, eliminating the need to transfer raw data back and forth for every parameter adjustment. This preliminary action reduces subsequent processing time while maintaining the ability to generate alternative images with different parameters.
2Adaptability or versatility
If SAR data is transferred to a remote data center for re-processing, then image generation capability is improved, but data transfer requirements and system complexity increase
Solution Approach 1:
The system implements multi-functionality by enabling the same SAR processing pipeline to operate in multiple modes: interactive local processing for rapid parameter exploration and remote cloud-based processing for generating alternative images with different parameters. The workstation can function both as an interactive processing station and as a data transfer node, while the remote data center serves both as a computation resource and a storage resource. This universality reduces overall system complexity by avoiding the need for separate dedicated systems for each function.
3Measurement precision
If iterative processing with different parameters is performed, then image analysis precision is improved, but processing time increases
Solution Approach 1:
The system applies local quality by performing rapid iterative processing with different parameters locally on the workstation using pre-processed intermediate SAR products, while reserving remote cloud-based re-processing only for cases where fundamentally different image products are needed. This allows analysts to perform multiple quick parameter adjustments locally for fine-tuned analysis, maintaining high precision while minimizing time losses by avoiding unnecessary remote data transfers for routine iterative exploration.
