Study of SAW ice sensor application to highway airstrip

Highway airstrips construct the airport net with stock airports and standby airports as assistant, and the icing condition of airstrip surface need be monitored. Surface acoustic wave(SAW) ice sensor is in small size and can wireless passive measure, potential in highway airstrip ice monitoring application. Based on Zimmermann's theory, the impacts of guiding layer thickness on phase velocity was studied in a practical experimental setting in which the guiding layer was SU-8 and the substrate was ST90° X quartz, The preparatory experiment was carried out to prove the Love wave ice sensor principle. The results show that Love wave ice sensor could distinguish air, water and ice clearly. The SAW ice sensor application scheme in highway airstrip was put forward according to the experimental results.
