摘要
将矩形平面阵的波束图等效为2个相互垂直的线列阵波束图乘积,通过计算这2个线列阵的加权值,再利用向量直积来获得矩形平面阵的加权值。计算机仿真表明,在近场下二阶锥规划法比常规的Chebyshev法具有更好的波束优化效果。
The beam pattern of rectangular plane array was considered to be equivalent to the product of two line arrays that were orthogonal with each other.After calculating the weights of line arrays,the vector product method was used to get the weight of rectangular plane array.Simulation shows that the beamforming optimization effect of second order cone programming algorithm is better than that of Chebyshev algorithm in near field.
