基于二阶锥优化的指定零陷宽度方向图综合研究

Array Pattern Synthesis Method with Prescribed Broad Nulls Based on Second Order Cone Programming

针对指定零陷宽度的方向图综合问题,在求解过程中将原模型的求解转化为一个二阶锥优化问题,采用内点法利用Sedumi软件进行求解,降低了运算量,相对于传统求解方法能够在指定的干扰区域方向获得更深的零陷,同时不限制于阵列流型,对于非均匀阵列依然适用。仿真结果证明了文中使用的基于二阶锥优化的指定零陷宽度方向图综合方法的有效性。

In this paper,the array pattern synthesis method for prescribed broad nulls was discussed. The original problem is transformed into a second order cone programming problem and solved using interior method by Sedumi,which decreases the calculation amount. Compared with traditional method,the new method can produce deeper nulls in the angle range prescribed,and it is suitable for array with nonuniform distances. Simulation result showed the efficiency of the new method introduced in this paper.
