摘要： 针对现有筒弹环境监测系统的缺陷和实际需求，利用声表面波传感测试技术，设计了一种基于SAW 传感器的无源无线筒弹环境监测系统，选用多种类谐振型SAW 传感器集成安装、共用天线的方式实现温湿压传感信息的同时读取，结合谐振型SAW 传感器反射信号特性设计了阅读器电路，实现了发射扫频信号，无线激励SAW 传感器，以及解调传感器反射信号的功能。

Abstract: Aiming at the defects and actual requirements of the existing launch canister environment monitoring system, a passive wireless cartridge environment monitoring system based on the SAW sensor was designed by using the surface acoustic wave (SAW) sensing technology, and a variety of resonant SAW sensors were selected for integrated installation. The method of sharing the antenna realizes the simultaneous reading of the temperature and humidity pressure sensing information, and combines the characteristics of the reflected signal of the resonant SAW sensor to design a reader circuit, and realizes the function of transmission of the sweep signal, the wireless excitation SAW sensor, and the demodulated sensor reflection signal.

Key words: Passive wireless, SAW sensor, Radio frequency communication
