Description

technical field

[0001] The invention relates to a passive atomic frequency standard, in particular to a method and device for combining advantages in a passive atomic frequency standard system; it can be widely used in navigation and positioning, Doppler speed measurement, synthetic aperture imaging, dynamic Passive hydrogen atomic frequency standards, passive rubidium atomic frequency standards, and passive cesium beam atomic frequency standards in tracking and other fields. Background technique

[0002] Compared with the high stability crystal oscillator, the passive atomic frequency standard has good long-term stability, especially the passive rubidium atomic frequency standard has very important application value in engineering because of its small size, light weight and low power consumption. However, due to the limitation of physical mechanism, the short-term stability index of passive atomic frequency standards is not good enough, which limits their application in eng...
