The article starts with the vibrating impact on the crystal oscillator in the radar frequency synthesizer, and analyses the phase noises of crystal oscillator under the random vibration condition. According to an airborne radar under the bad mechanical environment and the special installment, the vibrating isolation theory is used here to design elastic properties of vibration isolation system of crystal oscillator. The experiment has proved that the research of elastic properties of vibration isolation system of the crystal oscillator and measures taken to prevent the vibration are very effective. The research has not only solved the problem in present airborne vibrating isolation system, and also applied to all kinds of crystal oscillator in airborne radar.
