摘要：

This paper presents the method to generate frequency modulated continuous wave (FMCW) interrogation signal by using a phase lock loop (PLL) transmitter and NI ELVIS development board. The FMCW interrogation signal can be used for measuring temperature from a surface acoustic wave (SAW) sensor. The development of the PLL transmitter is discussed. The Arbitrary Waveform Generator of NI ELVIS is utilized for generating a linear frequency sweep reference signal, which will be used as a stable input signal for the transmitter. A MATLAB simulation using a pulse compression technique is performed to investigate the relationship between the FMCW bandwidth and range resolution.
