| 1. | We take the relation of grating - lobe between frequency , arrays commutation and concentric ring array into consideration , and select the proper elements for different frequency successfully . finally , adaptive digital beam forming of broadband signal in circular array are investigated 分析了在宽带信号情况下,如何从共形阵阵元中选择合适的阵元用作数字波束形成,并针对一应用实例进行了阵元选择设计。 |
