摘　　要：实验验证了一种基于电混沌信号测量电介质传输线故障的检测方法。该方法将改进型的Colpitts电路产生的混沌信号作为信号源,利用混沌信号相关法对传输线的开路点和阻抗失配进行了测量。实验结果表明,该方法结构简单且价格低廉,可实现电缆不同类型反射事件的识别。Experimental study of testing wire fault using electronic chaotic signal was performed.Chaotic signal generated by the Colpitts oscillator served as a probe signal.The breakpoint location and impedance estimation were detected by correlating the chaotic signal back-reflected from the fault with its delayed duplicate.The results show that this method was compact and cheep,and could measure several different kinds of wire faults.
