Ultra-Stable Range-Extended Chirped-Pulse DAS Using Coherent Detection

Not Accessible

Your library or personal account may give you access

Abstract

We present a coherent multifrequency demodulation CP-ΦOTDR system that allows the use of wide filters in detection instead of narrow and tunable filters. Additionally, this opens the door to the use of linear decoding techniques.
