analyze the linear dipole array with uniform element spacing using the method of moments ( mom ), derive the analytical expression for the recovered signal with the direct data domain method, demonstrate the effect of the mutual coupling on the performance of the antenna array by examples, the degradation of the system caused by the mutual coupling is simulated and analyzed in two different electromagnetic environments such as the weak and strong interference 用矩量法計(jì)算了幾個(gè)信號(hào)同時(shí)照射時(shí)對(duì)稱陣子均勻直線陣的電流分布,用直接數(shù)據(jù)域算法推導(dǎo)了此接收陣列的恢復(fù)期望信號(hào)的表達(dá)式,舉例說明了互耦對(duì)陣列天線性能的影響,數(shù)值模擬了在弱干擾和強(qiáng)干擾下,互耦造成系統(tǒng)性能下降的情況并分析了原因。
