提出了一种可用于实现各种线性约束自适应阵列处理器的波束形成结构。该结构被设计用于与已经被时间延迟操纵的阵列一起使用，使得感兴趣的期望信号在操纵输出处近似同相地出现。新结构的一个主要优点是可以使用简单的硬件差分放大器来实现约束。所示的结构，以纳入算法，已建议以前用于自适应波束形成，以及包括新的方法。它也是特别有用的研究导向误差对阵列性能的影响。数值例子说明了该结构的性能。
A beamforming structure is presented which can be used to implement a wide variety of linearly constrained adaptive array processors. The structure is designed for use with arrays which have been time-delay steered such that the desired signal of interest appears approximately in phase at the steered outputs. One major advantage of the new structure is the constraints can be implemented using simple hardware differencing amplifiers. The structure is shown to incorporate algorithms which have been suggested previously for use in adaptive beamforming as well as to include new approaches. It is also particularly useful for studying the effects of steering errors on array performance. Numerical examples illustrating the performance of the structure are presented.
