The Clock Synchronization Technology And Applications Based On High Order Correlation Properties

With the development of science and technology, clock synchronization and ranging technology in precision guidance, radar and space technology applications in more and more prominent, their precision and accuracy have higher requirements gradually. Because the traditional clock synchronization technology and positioning technology (GPS) is based on the classical theory of development, its accuracy and precision time positioning will be limited to the pulse signal bandwidth and power constraints, and therefore more accurate timing positioning technology on the most commonly States attention of researchers. In recent years, based on quantum mechanics and quantum entanglement properties of quantum information theory combining quantum clock synchronization and positioning technology to provide a breakthrough, not only to overcome the limitations of traditional bandwidth and power technology, but also has higher precision and accuracy degrees.This paper will be based on the basis of second-order quantum correlation clock synchronization, according to the higher-order correlation function is proposed based on the characteristics associated with high-end clock synchronization technology solutions and ranging systems, this design not only can be used for clock synchronization, but also can be used for ranging location. Mainly for second-order clock synchronization and accuracy ranging improvements were improving, it works as follows:1, According to the second-order clock synchronization technology and higher order correlation function theory is proposed based on the characteristics associated with high-end clock synchronization technology program, which uses high-intensity light in a pseudo heat source, for the entire synchronization system synchronization principle, synchronization accuracy and synchronization factors and SNR carried out a detailed analysis and research. The results showed that higher-order correlation synchronization system in the optical path of the order unchanged, by increasing the number of probes detector system in the optical path of the light field, which can not only improve the two clock synchronization accuracy, but also can improve synchronization noise ratio of the system.2, Designed based on high-end properties ranging system associated with its system of entangled light source with high brightness, and precise control of the repetition frequency of the pump light reaches the detector probe time control through the CPLD circuit, a detailed analysis and study principles and ranging ranging system affect the relationship between factors and the system optical path signal to noise ratio. The results show that higher order association ranging system within a certain range by increasing the number of samples collected optical system and detector order optical channel data can not only improve the signal to noise ratio ranging system, but also to get more than the traditional second-order ranging system and a higher quantum classical radiolocation technology and optical ranging technology accuracy and precision. Finally, the use of Matlab software simulation of their different distances ranging effects, results not only show its ranging accuracy can reach microns, but also that the ranging program design feasibility and accuracy.
