Abstract
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.
