中文摘要：

利用Matlab控制数字示波器,实现声表面波-射频识别（SAW-RFID）系统数据采集的功能,以获取示波器采集的标签编码回波信号。上位机在Matlab上进行了显示界面的设计,利用最大相关法对采集的回波信号作算法解调处理,最终完成了声表面波射频识别系统的搭建。

英文摘要：

MATLAB controlled oscilloscope was used to implement the acquisition of analog signal from the reader of SAW-RFID system,and to acquire the coded echo signal of the tag displaying on the oscilloscope.Data display could be designed in MATLAB on the computer and the coded echo signal of the tag was demodulated and processed with the maximum correlation method,thus SAW-RFID system was established in the end.
