Application of Wavelet in Airplane Cable Fault Location

A wavelet-based signal processing algorithm for airplane cable fault location is proposed in this paper. A Mallet orthogonal discrete wavelet decomposition and reconstruction algorithm is used to eliminate the noise in the aircraft cable fault signal. The experiment result has shown that the character of emission pulse and reflect pulse used to test the aircraft cable fault point are reserved and the high-frequency noise are eliminated by means of the proposed algorithm in this paper.
