Time Domain Reflectometry (TDR) Based Cable Fault Analyzer

Summary

This project, completed in partnership with General Dynamics Mission Systems, focuses on developing a device that uses time domain reflectometry (TDR) to detect and locate faults in twisted-pair communication cables used on U.S. Coast Guard Rescue 21 towers. The device combines both custom hardware and software to generate and analyze electrical signals, enabling accurate fault classification and distance measurement along cables up to 2,000 feet. By helping technicians quickly distinguish between cable damage and equipment failures, the device can reduce downtime and improve the reliability of critical maritime search and rescue operations.
