摘要 为减少大型相控天线阵的优化唯相权值的计算量,本文提出一种新的相控阵部分自适应波束形成的收发算法.它采用自适应部分地选择控制零点的控制阵元(PA),按照最大信干噪比原则,用部分唯相共轭梯度法计算各个阵元的优化唯相权矢量来减轻干扰的影响.模拟结果表明,当干扰数目小于阵元半数时计算性能有很大提高,同时天线远场模式的主瓣损失、波形变化及干扰方向零点深度与全阵自适应相比几乎没有变化. To lessen the computational cost of optimal weight phasor in massive linear isotropic phase-only arrays, a novel partially adaptive approach suiting for both beamforming receiving and transmission is presented in this paper. With this approach, array elements controlling nulls are partially selected adaptively (PA) and the optimal phasor is achieved by partial phase-only conjugate gradient algorithm to mitigate interferences according to the maximal signal to interference plus noise ratio (SINR). The simulations show that the computational performance will be improved greatly while the mainbeam loss,mainlobe shape distortion and nulls depth in the directions of arrival(DOA) of interference of the far-field pattern do not change significantly compared to the full adaptive (FA) case with assumptions that the number of interferences are less than half of the array elements and directions of arrival of interference are not in the mainbeam of the arrays.
