Wire on live detection technology is important to aircraft line fault detection. Spread Spectral Time Domain Reflectometry is an effective method for wire fault detection on live. For aviation field,this paper analyzed the principle of SSTDR,established the SSTDR simulation platform and built its experimental system with FPGA as the core. Both tests show that this method is effective for wire carrying high frequency communication signal. At last,based on the theory and experiment,obtained its accuracy of locating fault point,analyzed its scope of application.
