N2 - Reflectometry is a kind of cable fault diagnosis. There are various kinds of reflectometries such as time domain reflectometry(TDR), frequency domain reflectometry(FDR), and joint time-frequency domain reflectometry(TFDR). In this paper, we propose a new fault location estimation method using residual of AR coefficient estimation. Proposed fault distance estimation method models the reference signal as a simple second order AR coefficient, and estimates reference signal and reflected signal via robust weighted least square(RWLS) estimator. Using residual of estimation, proposed fault distance estimator estimates the fault location of the cable. The performance of the proposed method is verified by simulations and experiments.
