Study on FADS Based on Wireless SAW Pressure Sensors
NI Shi-hong · Micronanoelectronic Technology · 2007
FADS(flush air data system)is an advanced air data system.Because the pressure sensors are flush with aircraft surface,the system is convenient to be concealed and can work well in great march and great attack angle conditions.As the SAW pressure sensor can be used wirelessly,the wireless SAW pressure sensor can be conveniently applied to FADS.Working with MIMU devices,it could become a cheap miniature integrated navigation system.The principle of FADS,the principle of wireless pressure sensor based on double one-port SAW resonators and the circuit structure were studied,the wireless SAW pressure sensor was simulated by SAW resonator equivalent circuit with HP Esoft.The study suggests that wireless SAW sensor is potential for the advanced FADS and has great application value.
