Abstract

Systems and methods for performing loop analysis are described. Some embodiments are directed to determining loop characteristics such as loop gauge, loop termination, and straight-loop departure. One embodiment includes a method for performing loop length estimation which comprises receiving an un-calibrated echo signal for a loop under test using frequency domain reflectometry single-ended line testing (FDR-SELT), a region associated with the loop under test, and a platform type. The method comprises classifying the loop under test and outputting a loop length estimate based on the classification of the loop under test and based on one of a ripple-period approach and a template-matching approach.
