针对激光告警中来袭激光方向的确定，应用基于米氏散射的激光离轴探测模型，采用可以获取激光束传输方向上最大辐照度点位置信息的散射告警器对来袭激光方向进行测定。在此过程中选取两个激光告警器，根据激光束与告警器的不同位置关系，分两种情况计算激光束方向。经理论计算验证，在不增加探测器数量的情况下，该方法可以准确地确定任意来袭激光束方向，简化了探测系统。由于探测器的位置不受离轴距离等因素影响，故处理的数据较少，性价比高，实时性强。
針對激光告警中來襲激光方嚮的確定，應用基于米氏散射的激光離軸探測模型，採用可以穫取激光束傳輸方嚮上最大輻照度點位置信息的散射告警器對來襲激光方嚮進行測定。在此過程中選取兩箇激光告警器，根據激光束與告警器的不同位置關繫，分兩種情況計算激光束方嚮。經理論計算驗證，在不增加探測器數量的情況下，該方法可以準確地確定任意來襲激光束方嚮，簡化瞭探測繫統。由于探測器的位置不受離軸距離等因素影響，故處理的數據較少，性價比高，實時性彊。

In order to detect the attacking direction of laser from the enemy,scattering warning detectors with the capability to locate the maximum irradiance in the propagating direction of the laser beam are employed with the help of the Mie scattering theory.In the orienting,two detectors are needed to lay foundation for the different location relations with the object. Then discussion is conducted. Theoretical calculations and experiments demonstrate that the laser from arbitrary direction can be oriented.There are several evident advantages:firstly, the detecting system is simplified;secondly,the locations of the detectors are unrestricted by the off-axis distance or other factors;thirdly,the data to be processed are somewhat fewer.
