摘要
针对智能天线信源数目SH准则和AIC准则算法复杂,具有人为因素干扰,以及传统DOA算法主要针对线阵分析,达不到应有的精度和测量整个空间的目的。首先介绍传统智能算法,阐述了SH准则、AIC准则的原理,同时给出了改进算法模型,以及改进DOA估计的模型。实验结果表明,在白噪声干扰情况下,运用改进准则可以减少人为因素的影响,加快算法速度;改进的DOA估计可以降低白噪声的干扰,在整个空间上对接收信号进行了分析,提高准确率。
For the smart antenna source number SH criterion and AIC criterion with human disturbance algorithm are complex,and the traditional DOA algorithm for linear analysis fail to achieve the desired accuracy and measuring the spatial objective.This article first introduces the traditional intelligent algorithm,and expounds the principle of SH criterion,AIC criterion,and gives the algorithm model,and the model of improved DOA estimation.The experimental results show that,in the white noise case,by using the improved criterion can reduce the influence of human factors,accelerate the speed of the algorithm;improved DOA estimation can reduce the interference of white noise,in the entire space for receiving signals are analyzed,to improve the accuracy.
