摘　　要：从天线阵的一般模型出发，理论研究了方向回溯天线的实现条件，提出了广义相位共轭条件，统一分析了VanAtta阵和相位共轭阵（PON阵）两种典型方向回溯天线阵的工作原理，比较了两种天线阵列的优缺点。理论推导并给出方向回溯天线阵的单站和双站雷达散射截面的表达式，为方向回溯天线阵的进一步研究奠定了基础。On the basis of the general antenna array model, the necessary condition of retrodirective antenna is theoretically studied and derived, and the generalized phase conjugation condition is firstly proposed. The principles of the VanAtta array and phase conjuagtion array （PON） are analyzed, and the advantages and disadvantages of two typical retrodirective antenna array are discussed. The expressions of monostatic and bistatic RCS are theoretically derived. It lay a foundation for the further research of the retrodirective antenna array.
