摘要:
分析延迟线型声表面波（surface acoustic wave，SAW）传感器所接收射频脉冲查询信号传输特性理论，讨论在传感器中叉指换能器（inter-digital transducer， IDT）和反射器的尺寸、相邻反射器之间的距离、IDT与最近反射器之间的距离，以及在信号采集需求共同作用下，对SAW传感器返回的射频脉冲回波信号脉冲宽度的影响，计算给出射频脉冲查询信号的选取原则．该研究可供SAW传感器的结构设计及理论分析借鉴．
Abstract:
According to the theoretical analysis and experimental data analysis of the radio frequency（RF） pulse query signal transmission characteristics received by the surface acoustic wave(SAW) delay-line sensor, the pulse width of the RF pulse echo signal reflected by the SAW sensor can be affected by the size of the inter-digital transducer （IDT） and reflectors. The distance between the adjacent reflectors, the distance between the IDT and the reflector, and the selection method of the RF pulse width in the RF pulse query signal are discussed through the equations. Results presented in this paper can help designers to make better SAW sensor design and contribute to their theoretical analysis.
