Bartlett波束形成的波束零限权设计

为了抑制相干噪声源干扰,给出了一种Bartlett波束形成的波束零限权矢量设计方法,可以形成单个或多个波束指向性零点.经过理论推导给出了权的解析形式,其形式只与干扰源方位有关.与传统的自适应方法相比,它的权值不依赖于接收信号,因此具有更好的稳定性;当干扰方位确定时,权向量为只与干扰方位有关的固定形式,因此不需要实时计算,具有计算量小的优点.仿真结果表明,该权可以有效地对单个或多个干扰方向形成波束零限,且对旁瓣有一定降低作用,可用于抗相干噪声源干扰.

Designing null-forming weights based on Bartlett beam forming

In order to suppress coherent interference,a method for determining null-forming weights based on Bartlett beam-forming was developed.This method can form one or several zeros in terms of directivity.An analytical form of the weighting was deduced from theory.The weighting is only related to the orientation of the interference.Compared with the traditional adaptive method,the weights are not dependent on received signals,and therefore they have better stability.When the orientation of interference is known,...
