摘　　要：针对二极管阵列激光告警系统,介绍了激光告警天线的窗口布局,分析了水平及俯仰方向的激光方位识别原理,建立了激光威胁信号的方向识别模型。利用水平方向识别模型对某典型设备展开分析,深入开展了增大探测窗口视场对告警系统方位分辨精度影响的研究,为激光告警设备水平方向的识别提出了一种新的设计方案。通过对比分析得出结论:该方法在保持系统角分辨精度的情况下降低了告警系统的虚警率。与采用多元相关探测技术相比,激光告警系统探测单元减少了一倍,且体积小、功耗低、成本低。Detection window structure of warning antenna was introduced for the laser passive warning system based on photoelectric diodes array;laser orientation detection principle of horizontal and vertical direction was analyzed;orientation identification model of laser threat signal was also established.Making use of orientation identification model of horizontal direction,the typical laser passive warning system based on photoelectric diodes array was analyzed.Influence of augmenting window field of view（FOV） on laser orientation identification precision was researched,and a new scheme of horizontal direction laser orientation identification was proposed.The analysis result shows that the system orientation identification precision of laser threat signal is retained after the scheme being introduced into the laser passive warning system,and the false alarm probability of laser warning system is reduced.The new scheme brings simpler detection circuit,smaller size,lower energy consume,and lower cost to the laser warning system than the multiple-unit correlated detection scheme.
