有较好的参考价值，用于信号特征提取、信号消噪，多目标跟踪的粒子滤波器，借鉴了主成分分析算法（PCA），直线阵采用切比学夫加权控制主旁瓣比。- There are good reference value, For feature extraction, signal de-noising, Multi-target tracking particle filter, It draws on principal component analysis algorithm (PCA), Linear array using cut than learning laid upon the right control of the main sidelobe ratio.
