摘要:
针对非均匀天线组阵中常用的SUMPLE与PMFM(Proposed Matrix-Free Method)算法合成性能较差的问题,分别在SUMPLE与PMFM算法模型中引入对角加载技术,提出了一种新的信号合成算法。该算法利用权值幅度估计各路噪声功率,并对角加载到权值迭代算法中以得到准最优复权值向量。理论分析与数值仿真均表明,在不明显增加计算量的基础上,新算法在非均匀组阵中的合成损失明显低于SUMPLE与PMFM算法,同时新算法的收敛速度也与各自模型算法相当,因此更加适用于实际组阵系统,具有重要的工程应用价值。

Abstract:
A new combining algorithm for non-uniform arraying is proposed to improve the poor performance of the SUMPLE and PMFM(Proposed Matrix-Free Method)algorithm,by applying diagonal loading technique to the SUMPLE and PMFM algorithm model separately. The proposed algorithm,which is diagonal loaded by the estimated noise power based on the weight amplitude,can solve the quasi-optimal weight vector iteratively. Theoretical analysis and numerical simulations show that the novel algorithm can achieve obviously lower combining loss for non-uniform antenna arraying,with similar computation complexity and convergence rate to the SUMPLE and PMFM model algorithm. Therefore,it is a strong candidate for engineering application in the actual antenna arraying system.
