Performance Improvement of Dual-Pulse Heterodyne Distributed Acoustic Sensor for Sound Detection
Phase fading is fatal to the performance of distributed acoustic sensors (DASs) influencing its capability of distributed measurement as well as its noise level. Here, we report the experimental observation of a strong negative correlation between the relative power spectrum density (PSD) at the het...
