在实现具有良好抗干扰能力的阵列宽带波束形成的过程中,经常要面临宽零点约束的方向图综合问题。提出了最小最大旁瓣宽零点约束算法( MMSLC),优化了波束对消器零点的设置方法,以比传统的算法减少所需设置的零点数目,实现了宽零点约束的方向图,提高了圆阵宽带波束形成算法的有效性。仿真结果显示MMSLC算法较传统算法的优越性。

In the process of realizing array wideband beamforming with well anti?interfere properties, researchers are often faced with the problem of array pattern synthesis with broad null constraint. By using the principle of minimum mean square error ( MMSE) , the optimal synthesis method of array side?lobe cancellers based on optimum min?max side?lobe constraint ( MMSLC) algorithm is given in this paper. The algorithm optimizes the ways of setting zeros of beam cancellers, decreases the number of setting zeros required in traditional algorithms, realizes the broad null constraint pattern, and improves the validity of circular array wideband beamforming algorithms. The simulation showed that MMSLC algorithm improves the performance of beam cancellers, and it is superior to the traditional al?gorithms.
