摘要

在本文中，我们提出了一种解决在单个讯问系统范围内访问多个被动表面声波(SAW)传感器问题的方法。利用bpsk编码传感器的相关特性，几乎同时对声表面波传感器的传感器信息进行评估。我们展示了声表面波传感器系统的基本概念，数学模拟，数值估计，最后概述了这种传感器系统的设计。

Multiple access to SAW sensors using matched filter properties

In this paper we present a method of solving the problem of access to more than one passive surface acoustic wave (SAW) sensor in the range of a single interrogation system. The sensor informations of the SAW sensors are evaluated almost simultaneously by use of the correlation property of BPSK-coded sensors. We show the principal concept, mathematical simulations, numerical estimations and finally an overview of the design of such a SAW sensor system.
