摘　　要：本文研究了天线阵元间互耦对最大熵谱估计测向性能的影响,阐明了互耦使测向性能下降的机制,提出了一种能克服互耦影响的改进方法。计算机模拟结果表明,改进的最大熵谱估计测向方法在很大程度上提高了测向的精度和分辨率。In the paper the effects of mutual coupling among antenna elemerts on the performance of bearing estimation based on the principle of maximum entropy and the mechanism of the performance degradation due to the mutual coupling are studied. A modified method is proposed to counteract the mutual coupling. Computer simulation results show that the modified method has some significant improvement over the original method in resolution and accuracy of bearing estimations.
