摘要
Abstract
An improved nonlinear least-square method is presented in this paper.By introducing in-vasive weed optimization,the initial solution and the global best solution in each iteration process are se-lected.The problem of instability of nonlinear least-square method is solved.Given the determinate ele-ment number and array distribution,the phase of excitation is optimized to shape array pattern,whose sidelobe facing to ground is suppressed and back to ground descends by steps.Compared to unweighted pattern,the optimized pattern can reduce cluster level from the angle near main beam effectively.Simula-tion results prove the feasibility and efficiency of the method.关键词
