摘要

加载可加速ＳＭＩ算法的波束收敛，本文给出给定快拍下达到波束收敛所需加载量的近似计算公式。分析表明加载还可加速算法的信干噪比收敛，强副瓣干扰下使用本文的加载计算公式可在很少快拍数下达到信干噪比及波束形状的同时收敛。数值模拟结果证实了理论分析的正确性。

Abstract

When the SMI algotithm is used in ADBF

the convergence rate of beam pattern can be sped up by diagonal loading.In this paper

we give the proper loading level which is determined by some physical parameters.Both SINR and beam pattern can be rapidly converged with proper loading when strong interferences are impinged on sidelobe.Simulation results are given

which verify the theoretical predictions.
