摘　　要：基于广义相位共轭条件,研究了相位共轭天线阵实现方向回溯功能的原理,详细分析了射频混频和中频混频两种实现方式的工作方式并讨论了各自的优缺点。理论推导了相位共轭天线阵的远场表达式,提出了射频泄漏系数的概念,仿真研究了射频泄漏系数对方向回溯场的影响,为方向回溯天线阵的进一步研究奠定了基础。On the basis of the generalized phase conjugation condition,the principles of phase-conjugating arrays(PON)is theoretically studied and derived.The principles and the advantages and disadvantages of two typical PON antenna array of the realization of phase conjugation are analyzed and discussed.The far field expressions of phase-conjugating arrays are theoretically derived.The RF leakage coefficient is first proposed,and discussed the RF leakage coefficient on the impact of retrodirective far field.It lay a foundation for the further research of the retrodirective antenna array..
