| 摘 要： | 提出了一种基于ADS半物理平台的声表面波标签测试方法。采用矢量网络分析仪实际测试声表面波标签实物的S参数,在ADS软件中构建标签的物理抽象模型,并虚拟构建标签激励信号,利用ADS瞬态仿真功能获得标签回波信号,再采用MATLAB对回波进行数字正交解调,从而客观准确地测量标签各反射栅的时延、相位。最后通过搭建的半物理平台对声表面波标签进行了测试,表明了ADS半物理平台的有效性。 |

| Abstract: | To test the surface acoustic wave (SAW) tag, the ADS semi-physical platform is proposed. This method utilizes the vector network analyzer for the measurement of the S parameters of the SAW tag, and establishes its abstract model in the ADS software. With the virtual excitation signal in the ADS, the echo signal of the tag is obtained by the ADS transient simulation function. The digital quadrature demodulation is implemented by the MATLAB software to measure the time delays and phases of the reflectors on the tag objectively and accurately. The SAW tag is tested by the above mentioned semi-physical platform, and the measurement results show the effectiveness of the ADS semi-physical platform. |
