摘　　要：首先对方向图的综合问题进行描述,然后介绍了半正定优化方法,并结合半正定优化理论给出了一种线性阵列天线方向图的数值合成方法。将方向图的综合问题,经过数学推导,转换为半正定优化(Semi definite Programming,SDP)问题,通过内点方法获取最优权值。最后进行一组仿真实验,并对结果进行分析。实验结果表明了该方法的有效性和稳健性。This paper first describes the problem of pattern synthesis, then presents the methods of semi- definite programming,and it is concerned with the pattern synthesis for linear array. The design problem is shown to be convex, and its Semi- definite Programming （SDP） formulation is obtained that facilitates a computationally efficient way to implement our design using the interior point method. Lastly,we do a series of experiments and make an analysis of the experiment results. The results demonstrate the effectiveness and robustness of the proposed algorithms.
