摘　　要：本文分析了对角线加载对自适应阵性能的影响，提出了加载门限的概念，以及加载门限的计算公式，为加载量的选取提供了方法和依据；并将加载研究的结果加以推广，提出了有效的ＬＳ自适应波束形成算法的非零初始化方法．In this paper,the effect of diagonal loading on adaptive array performance is analyzed . The di-agonal loading level threshold is defined under the measure that the adaptive array SINR loss is less than 3dBand is analyzed for different interference cenarios.The results are meaningful for determining the loading level.Based on these results, an effective approach of nonzero initialization for recursive LS adaptive beaforming algo-rithms is proposed.
