摘　　要：非均匀阵列由于其孔径大、自由度高的优势逐渐被广泛应用,但已有的方向图综合方法不再适用于非均匀阵列。为此,针对对称非均匀阵列,提出了一种解析的方向图综合方法。该方法包含2个步骤。第一步,通过凸优化方法获得一个实对称激励以生成笔状波束;第二步,将指向不同方向的笔状波束进行叠加生成期望的方向图。仿真试验结果验证了该方法的有效性,且具有较大的工程价值。Nonuniform arrays are gradually widely used for the advantages of large aperture and high freedom degree,but the existing pattern synthesis methods are no longer suitable for them.To this end,this paper proposes an analytical pattern synthesis method for the symmetric nonuniform array.This method consists of two steps.In the first step,a real symmetric excitation is acquired by the convex optimization method to generate a pencil beam.In the second step,the pencil beams pointing in different directions are superposed to synthesize the expected pattern.The simulation test results verify that the proposed method is effective and has great engineering value.
