摘要
自适应波束形成技术是相控阵雷达抗干扰的一种重要手段,目前提出的许多有效方法都是基于阵元级线阵自适应波束形成方法,而实际的相控阵雷达系统多采用阵面结构。结合线性约束最小方差(LCMV)算法,研究了一种子阵级波束合成抗干扰方法。在目标方位接收功率不变的条件下,最大限度抑制干扰方向信号接收。
Adaptive beamforming technology is an important method for phased array radar anti- jamming. At present, many effective methods are based on element stage linear array. And the actual phased array radar is used in planar array structure. An anti-jamming method of sub ar- ray level is studied by LCMV algorithm. The interference direction signal is suppressed furthest under the condition of constant target signal power.
