Recent evolutions of pulse correlation sensing system system for reliable, high resolution, wide dynamic range and region selectable distributed environment sensing

Novel pulse correlation sensing system was proposed for wide region environmental distributed monitoring. Using very simple technique and optional component, the performances of signals polarization stability, sensitivity, and sensing dynamic range are dramatically improved. In addition, feasibility of a novel sensor interrogation scheme that combines the advantages of the distributed and point sensor systems using a robust interrogation technique are proposed. The high linearity, sensitivity and stability of the measurements for infrastructure requirement monitoring are successfully obtained.
