Research on Adapted Pattern Null Widening Techniques

在自适应天线阵抗干扰的一些应用环境中 ,往往需要自适应天线方向图在对准干扰的位置形成宽的零陷从而增强算法的稳定性。本文从统计模型的角度出发 ,导出一种对干扰零陷加宽的自适应波束形成方法 ,该方法能在由于数据失配引起的干扰位置扰动的情况下有效地抑制干扰 ,大大增强了算法的稳定性 ,并且方法简单、所增的运算量很小。

It is often desireable to widen the interference null width in an adapted pattern to impart robustness into the realized adapted pattern in some real environments. In this paper, an adapted pattern null widening method is derived from a statistical model. It can reject effectively interferences when the perturbation of interference locations occurs. Moreover, this method is simple and easy processing. Computer simulation results are presented for illustration.
