Time-frequency signal distribution and transmission technology based on optical fiber WDM

Abstract： In order to ensure the efficiency of signal synthesis between multiple channels in a digital phased array, the system needs to provide highly stable time-frequency signals for multiple sub-arrays of the phased array. There is a problem of poor amplitude and phase consistency in the method that the traditional phased array uses cables to directly distribute and transmit. In this paper, a time-frequency signal distribution and transmission technology based on optical fiber wavelength division multiplexing is proposed, which can effectively solve the problem of efficient and stable distribution and transmission of time-frequency signals in digital phased arrays. The amplitude of each branch signal after distribution and transmission varies with temperature within ±0.5 dBm, and the phase varies with temperature within ±3°. The time-frequency signal distribution and transmission technology has been successfully applied to a digital phased array multi-target unified measurement and control system.
