摘　　要：在直线阵自适应方向图综合算法的基础上,提出了一种将平面阵转化为两个正交的直线阵,对两个直线阵分别应用直接矩阵求逆(DMI)的计算方法,该方法能正确地计算得到权值W。计算结果表明该方法实现了对平面阵主瓣形状、旁瓣电平、零陷的任意控制。A new synthetic method of adaptive plane arrays is proposed based on adaptive algorithm of linear arrays pattern. The plane arrays are transformed into two linear arrays. The Least Mean Square（LMS） and Direct sample Matrix Inverse（DMI） methods are applied to the two linear arrays to obtain the value of W. The mainlobe shaping, sidelobe levels and null can be controlled efficiently. The results demonstrate the method＇s correctness and feasibility.
