外部物件中发生可截获的错误。
外场实验结果表明：该方法可有效地提高激光雷达的测距能力，迎头截获距离可提高约2 ~3倍。
External experimental results show that the method can improve the detection distance of the laser radar, and the head-on intercept capture distance can improve about 2 ~ 3 times.
将截获信号的直观几何特征（星座图）映射到变换域中，可区别不同调制内部的同相正交分量的相对关系，避免了聚类算法受噪声干扰和其他随机因素影响。
The novel feature distinguishes relative distribution between in-phase and quadrature components and lightens the great influence caused by noise and other random factor in clustering algorithm.
