摘要:
提出了一种微波反射式识别系统的实现方案,介绍了该系统的射频电路工作原理,分析了ASK反射调制方式和PSK反射调制方式对系统性能的影响,同时也探讨了系统在移动环境下的适应性,导出了该系统工作距离的理论估算公式.最后,介绍了该方案的实验情况,实验系统能在反射卡运动速度达到65 km/h的情况下稳定工作,说明本文的方案具有很好的移动性能,在非移动环境下,实验系统的最长有效工作距离达到8 m,有力地证明了该系统方案具有远距离应用的潜力.
Abstract:
A new RF solution to be used in microwave reflection tag identification system is introduced in this paper. System performances under PSK and ASK modulations are analyzed, as well as its adaptation in mobile situation. An up link distance estimation method is also introduced at the end of this paper. Experiment results show that the circuits work perfectly on high target speed up to 65 km/h, while also featuring a long up link range as far as 8 m. It confirmed that the solutions have great potential on long range applications.
