Abstract

Characterized by compression of polarization multiplexing LFM signals using MIMO in fractional domain, the interference-fading-free φ-OTDR is experimentally validated. The sweep bandwidths of LFM signals for orthogonal polarizations completely overlap, resulting in ultrahigh spectrum efficiency.
