基于微波光子技术的二相和四相编码信号产生研究
Generation of Binary and Quarter-Phase Coded Microwave Signals Based on Microwave Photonics
摘要
Abstract
To solve the problem of limited carrier frequency and insufficient modulation rate of phase coded signal by electronic bottle-neck,photonic generation of binary and quarter-phase coded microwave signals by using a single dual-polarization quadrature phase shift keying modulator(DP-QPSKM)is proposed.In the approach,QPSKM1 is driven by RF signals to generate frequency shift lightwaves,while QPSKM2 is driven by baseband signals to generate phase-shift key lightwaves.After combining the two lightwaves from DP-QPSKM,binary and quarter-phase coded microwave signals can be generated by square-law detection in photoelectric detector.The frequency of the generated signals is twice that of the injected radio frequency,offering advantages of generating high carrier frequency signal.The baseband signal is injected into the RF port of the modulator,ensuring that the phase coded signals has a high bit rate.Binary and quarter-phase co-ded microwave signals are generated by a single scheme,showing good reconfigurability.The proposed approach is verified by simulations.Binary and quarter-phase coded microwave signals with frequency of 16 GHz and bit rate of 2 Gbit/s are generated.The pulse compression performances of the generated signals are verified by auto-correlations.The proposed approach features the advantages of simply structure,good tunability,being filter-free and separated outputs,which has potential application in modern radar system.关键词
