Summary
This study introduces a new file management method for airborne radar data storage. It optimizes data writing to reduce response times and ensure even wear on storage components.
Area of Science:
- Aerospace Engineering
- Computer Science
- Data Storage Technologies
Background:
- Airborne radar systems generate high data volumes, exceeding air-to-ground transfer rates.
- Traditional file management methods for onboard data storage suffer from performance and wear issues.
Purpose of the Study:
- To address the limitations of traditional file management in airborne radar data storage.
- To propose and validate an optimized file management method for improved performance and longevity.
Main Methods:
- Developed a novel file management technique optimizing data writing across file allocation tables (FAT), file directory tables (FDT), and data regions.
- Implemented and tested the proposed method on an airborne radar data storage system.
Main Results:
- Significantly reduced the update frequency of the FAT and FDT.
- Achieved wear leveling between the file area and data region, enhancing storage system durability.
Conclusions:
- The proposed file management method effectively mitigates performance bottlenecks and uneven wear in airborne radar data storage.
- This optimization is crucial for reliable and long-term operation of onboard data storage systems.
