Abstract

Apparatus, systems, devices and methods for providing an orthognal frequency coding technique for surfaced acoustic wave sensors incorporating the use of multiple parallel acoustic tracks to provide increased coding by phase shifting and delaying a code sequence. The surface acoustic wave sensor includes parallel tracks with multiple reflectors with differing delay offsets to form a complex code sequence. The reflectors may be uniform, but alternatively could include fingers withdrawen, have reflector position modulation, differing frequencies or be spatially weighted.
