| 摘 要： | 大型相控阵天线有成百上千个阵元，子阵级的自适应波束形成技术能在保证良好的处理性能下有效地降低运算量。相控阵天线除了要自适应抑制强干扰源之外，还要求在强杂波背景下具有低或超低副瓣电平。采用归一化的数字波束形成方法来降低子阵的旁瓣电平。仿真结果表明，该方法能保持良好的阵列方向图，有效地抑制干扰并降低旁瓣电平。

| Abstract: | At present,large phased antennas have hundreds of elements,sub array-adaptive digital beam forming (DBF) can reduce computing complexity effectively with suboptimum performance. Phased antennas have the ability of adaptive interference suppression. Besides,it must have low side lobe or super low side lobe in strong clutter. Use unitary DBF method to reduce sub array side lobes. Simulations show that the method could keep excellent array direction figures with effective adaptive interference suppression and ... |
