LI Kai, ZHANG Hai-tao, LIU Wei-feng. Simultaneous extraction method of sensitive information for multiple OFC-SAW sensors[J]. 2016, 35(1): 36-38+42. DOI: 10.13873/J.1000-9787(2016)01-0036-03.
Simultaneous extraction method of sensitive information for multiple orthogonal frequency encode surface acoustic wave( OFC-SAW) sensors is discussed
and a multiple OFC-SAW sensor sensitive information simultaneous extraction system is designed. The amplitude and time delay of each OFC reflection signal is calculated by relationship equation group of same center frequency superposition signal and the OFC signal
sensitive information is extracted by delay difference of reflected signal. Simulation analysis verifies that the method is correct and effective.
