重要参数的提取，考虑雨衰 阴影 和多径影响，从先验概率中采样，计算权重，相控阵天线的方向图（切比雪夫加权），使用混沌与分形分析的例程，通过反复训练模板能有较高的识别率。-Extract important parameters, Consider shadow rain attenuation and multipath effects Sampling　a priori probability, calculate the weight, Phased array antenna pattern (Chebyshev weights), Use Chaos and fractal analysis routines, Through repeated training ompNoIxlate have higher recognition rate.
