摘要

广角扫描相控阵由于相互耦合的影响，带宽受到限制。如果阵列是规则的，即使在2:1的带宽比下，波段内的主动反射系数也会出现盲扫描异常。然而，如果阵列具有随机分布的元素，我们可以看到相互耦合的影响如何在主动反射系数中随机化，有效地增加了频率和扫描范围带宽。

On the effects of mutual coupling in the active reflection coefficient of wide-field scanning electrically large random phased arrays

Wide-angle scanning phased arrays suffer from bandwidth limitations due to the effects of mutual coupling. If the array is regular, blind scan anomalies can be found in the active reflection coefficient in band for even 2:1 bandwidth ratios. If the array has a random distribution of elements however, we can see how the effects of mutual coupling randomize out in the active reflection coefficient, effectively increasing the frequency and scan range bandwidth.
