摘要
本文对超声测距中回波信号的波形及频谱进行了分析,对其在测井电缆中传输问题进行了讨论。以此可作为选择测井电缆的电参数和有关电路设计的依据。
The waveform and frequecy spectrum of echo signal in ultrasonic range-finding are analyzed and the problems when vltrasonic electrical signal is transmitting through the logging cables are discussecl.This paper provides scientific basis for choosing parameters of fogging cables and the design of circuit concerned.
