CATING SYSTEM FOR WAVEGUIDE TRANSMISSION LINE UTILIZING SPACED REFLECTORS

摘要

Faults having negligible reflectivity but causing substantial signal loss in an overmoded waveguide transmission line can be located by utilizing reflectors spaced at substantially equal intervals along the line. Return loss from these reflectors is measured and faults localized between any two of such reflectors by detecting any departure of the return loss from a linear increase with distance.
