Impulse Measurements of SAW Sensor with Ultra-Wide-Band Hyperbolically Frequency-Modulated Reflectors

A Surface Acoustic Wave sensor including grooved-grating chirp reflectors are designed to exploit Ultra-Wide-Band Hyperbolically Frequency Modulated signals. The study results have been published in our previous works. The purpose of this work is to investigate features of SAW temperature sensors with implemented HFM technology using radio frequency impulse signals in a wide frequency band.
