摘要：In this paper, for the problem that the cables in aircraft power system are complex, numerous and hard to detect, the method based on chaotic spread spectrum sequence for synchronous online diagnosis of complex cable system is proposed. The proposed method can solve the limitation of the cables' number that can be diagnosed synchronously in spread spectrum time domain reflectometry (SSTDR). The model of chaotic spread spectrum sequence is established, and the research shows that its pointed autocorrelation characteristic can be applied in single cable fault diagnosis, and its good cross-correlation characteristic can be applied in multiple cable faults diagnosis. With the large number of chaotic sequence, the proposed method can be extended to online diagnosis of multiple cable faults. The experimental results show that the method of chaotic sequence can effectively realize the synchronous diagnosis of multiple cable faults, with the location error within 20cm and the detection rate above 90%. © 2018, Chinese Institute of Electronics.
