摘要
本文从超声波信号模型出发,对超声电视测井井下仪器的接收机、发射机的指标和方位检测精度进行了详细分析.导出了对电路设计的要求,分析了系统可能达到的指标.电路试验与系统指标测试表明,本文的分析方法正确,其数学方法亦可供其它有关超声仪器分析时借鉴.
With a model for the ultrasonic signal, the requirement on receiver and transmitter performance and the detection accuracy of the bearings of an ultrasonic borehole televiewer are discussed. The circuit layout and possible system performance are analyzed. Experimental results show that the analyzing method presented is correct.
