Extraction methods of front-end signal feature parameter of wireless passive pressure sensor are researched.Sensor resonant frequency is determined by extraction of impedance real part,impedance phase,voltage peak value of antenna-end according to characteristic of front-end feature parameter of wireless transmission system in resonance.The experimental tests show that the difference between measurement results and theoretical value of measurement method of sensor resonant frequency based on impedance real part is minimum.
