Broad-Bandwidth Distributed Acoustic Sensor with Enhanced Robustness
We propose a novel sequence to compensate offset and sensitivity fading in FDM-<tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\phi$</tex>-OTDR without relying on specific frequency components, achieving 34.0 dB spurious-free-dynamic-range (SFDR) with a 9 kHz sinusoidal strain on a 10 km fiber.
