基于一种非等距线阵的宽带信号处理方法

摘要

In order to get the doa of broadband signals is proposed based on a non-uniform linear array method. At first make use of the Sunzi theorem verify the condition of the non-uniform linear array solving ambiguity, then make use of the condition of the non-uniform linear array solving ambiguity to construct a kind of non-uniform linear array. Adopt division frequency band phased array, the array interpolation techniques to compensate between the different frequency bands, then synthesizes and keeps the consistency that the array points to the different frequency and attain the signal power the coherent accumulation effect. At last, by the addition of before and after, get the doa. Simulation experiments show the effectiveness of this method.%获得宽带信号的波达方向,提出一种基于非等距的参差线阵方法.利用孙子定理、解模糊条件、分频带相控阵等方法解释非等距线阵.构造出的参差线阵通过处理合成,保持阵列对不同频率指向的一致性,达到信号功率非相参积累的预期效果.解模糊得到信号的波达方向,通过实验仿真验证方法可行.
