摘要 基于静态波束控制技术(Quiescent Pattern Control),提出了一种新的适用于天线零陷加宽的新方法,该方法通过对得到的最优权值按照最小均方误差准则进行二次约束计算出新的权值,从而获得在干扰方向较宽零陷的静态方向图。理论分析和计算机仿真表明,该方法能够很好地克服干扰运动和接收天线平台运动或者震动时对输出信噪比造成的不良影响,具有很好的稳健性。 A new technique is presented to widen nulls of adaptive antenna array pattern based on quiescent pattern control method. A novel weight vector based on minimum-square error with quadratic beampattern constrains is presented by proper choice the width of nulls and desired beampatterns in each region, and broad nulls can be gotten in the beampattern. Numerical results are presented to illustrate the performance achievable.
