- 阵元失效会破坏拖曳线列阵的幅相分布,导致阵列的旁瓣级出现明显升高,严重影响了阵列的性能。阵元失效条件下 的波束形成是一个非线性的最小平方的优化问题,对其直接求解非常困难。针对这一情况,提出了一种基于遗传算法的阵元 失效校准方法。算法的基本思想是将失效阵元的权重强制为零,并使得阵列的实际响应与期望响应在主瓣区域相匹配,同时 对阵列响应的旁瓣级作出限制-Failed elements will des仃oy the amplitude and phase distribution and

Robust-Beamforming-via-Semidefinite
- 现有的向量加权稳健波束形成方法只有在指向误差较小的情况下才能有效估计目标的信号功率;矩阵加权波束形成方法在指向误差较大时,虽然可以估计目标的信号功率,但是它的系统实现复杂度与向量加权稳健波束形 成方法相比较大。针对以上问题,该文提出基于半正定秩松弛(SDR)方法的稳健波束形成,该方法优化模型中的目标函数与Capon 算法的目标函数相同,优化变量为加权向量的协方差矩阵,并约束方向图的主瓣幅度波动范围、旁瓣电平,协方差矩阵的秩为1。-The existing vector weighted ro
