| 摘 要： | 提出基于SMI—LMS的自适应旁瓣干扰抑制算法，即利用采样矩阵求逆（SMI）算法计算初始权值，并以此作为LMS算法的初值。通过比较分析LS-LMS和SMI—LMS的方向图增益和运算量，并运用对角加载技术对SMI-LMS算法作出改进，验证了SMI-LMS算法的优势。仿真实验表明，SMI-LMS算法具有快的收敛速度和低的算法复杂度，在低快拍下有着好的性能。

| Abstract: | A new adaptive sidelobe interference suppression algorithm based on SMI-LMS is put forward.Sample Matrix Inversion(SMI) algorithm calculates weight vector as initial value for LMS algorithm.Through comparing the adaptive beam sidelobes and calculating quantity of two algorithms(SMI-LMS and LS-LMS),and improving the SMI-LMS algorithm by loading method,the SMI-LMS algorithm's advantage is approved.Regardless of the interference environments,this algorithm converges to the optimal value with a faster converge ... |
