| 摘 要： | 本文通过实验验证了一种基于宽带混沌信号测量电介质传输线的断点和阻抗失配的方法.该方法利用光反馈半导体激光器产生的混沌信号作为探测信号,通过相关法对传输线进行断点定位、阻抗失配测量以及在线检测.实验结果表明,断点的定位偏差小于1%,阻抗的测量值在额定范围内,对于频率为2 MHz的矩形脉冲信号的干扰容限为48 dB.

| Abstract: | We demonstrate experimentally a method to measure breakpoints and impedance mismatch for dielectric transmission lines by using broadband chaotic signals. Chaotic signal serving as a probe signal is obtained from the chaotic laser diode with optical feedback. Correlation method can realize breakpoint location, impedance estimation, and live test. Experimental results show that the location deviation is less than 1%, the impedance error is within the nominal rating, and interference margin is about 48 dB for 2 MHz square pulse signal on wire. |
