中文摘要：

为了研究不同几何分布的宽带阵列对互耦效应的适应能力,建立了一种互耦条件下新的宽带阵列天线接收数据模型。基于该模型比较了互耦效应对各种测向方法性能的影响,以及几种常见阵列结构对互耦效应的适应能力。最后提出了一种宽带互耦补偿的思想,利用各频率点上互耦矩阵的测量值实现了对宽带阵列的互耦补偿。

英文摘要：

A new model of the wideband array output in the presence of mutual coupling is constructed to study the adaptability of arrays with different shapes to the mutual coupling effect. The performance deterioration of the narrowband and wideband direction finding methods due to such array imperfection is studied via simulations, together with a comparison in adaptability among arrays with different shapes. Finally, a mutual coupling compensating method, which exploits the array mutual coupling impedances at discrete frequencies within the signal bandwidth, is proposed to mitigate the influence of mutual coupling on the direction finding methods.
