摘　　要：基于仿生奥米亚棕蝇听觉机制建立的测向阵列,通过外加耦合电路可以实现相位差放大,从而达到提高小孔径测向精度的目的。以两阵元小孔径天线阵列为例进行仿真分析,表明即使在无外加耦合电路时,天线单元间的互耦同样存在类似于奥米亚棕蝇机械耦合的电磁耦合效应,实现天线阵列间的“相位放大”,且天线间“相位放大”系数随互耦增大而增大。The small aperture direction finding antenna array based on Ormia Ochracea,with external coupling network,can enhance phase difference of the received signals.In this paper,we present a model for twoelement antenna arrays that only takes the mutual coupling effects into account,that mimic the sense of directional hearing of the parasitoid fly Ormia Ochracea,it was demonstrated that these antenna arrays enhanced phase difference of the two element without external coupling,and the phase difference will be enhance as the raise of mutual coupling.
