激光引信如何抗云、烟环境干扰一直以来为该领域的研究热点。利用人工实体目标反射与烟雾后向散射回波的偏振度差异，设计了一种基于偏振探测的激光引信。该探测系统对烟雾后向散射信号产生消光效应远大于目标探测信号，选择性的降低了引信接收烟雾后向散射信号的能力。并结合激光引信的阈值探测原理和探测概率曲线，理论计算了该偏振探测系统对烟雾的探测概率降低到原探测系统的0.4%。最后结合工程研制经验，分析了该探测系统通过系列措施，既能保证其对目标的探测，又可大幅降低对烟雾的探测概率，而有望成为本质提高激光引信抗环境干扰的新方法。

Anti-interference of cloud and smoke is a hard problem for laser fuse. In this paper, a technology of polarization dection was presented based on the polarization degree difference in reflection of artificial entity targets and backscattering of smoke. The backscattering signal received by laser fuse was redused selectively as the extinction effect on smoke backscattering signal was much larger than the target reflection signal. The detection probability calculated theoreticaly has been reduced to 0.4% of the original detection system by using the principle of threshold detection and detection probability curve. Finally, analysis shows that the system was expected to be a new anti-interference method since it can not only detect the target but also reduce the detection probability of the smoke significantly according to the experience in engineering development.
