摘　　要：为研究激光制导武器在海上、陆上等各种环境下捕获目标的能力,建立激光制导武器飞行轨迹、后向散射、目标漫反射等数学模型,通过比较激光制导武器视场角、后向散射功率密度、目标漫反射功率密度来判别制导武器是否能正常捕获目标。设置相关参数后仿真计算表明在相同的条件下,相同的激光武器在海上相比于在陆上等环境中捕获目标时间更晚,捕获距离更近,后向散射更加严重。一般情况下激光制导武器在本照本投初始4.4s时间阶段内后向散射影响较为严重,通过降低激光照射器的出口能量或拉大激光制导武器中轴线与激光照射器光路距离至250m以上可规避后向散射的影响。In order to study the ability of laser-guided weapons to capture targets in various environments such as sea and land,mathematical models such as flight trajectory,backscatter and target diffuse reflection of laser-guided weapons are established,and whether the guided weapons could capture targets normally are judged by comparing the field of view,backscatter power density and target diffuse reflection power density of laser-guided weapons.Simulation calculations show that under the same conditions,the same laser weapon captures the target later at sea than in the land and other environments,the capture distance is closer,and the backscattering is more serious.Under normal circumstances,the backscattering effect of laser-guided weapons is more serious in the initial 4.4s time period of this projection,and the backscattering effect can be avoided by reducing the outlet energy of the laser irradiator or increasing the distance between the central axis of the laser-guided weapon and the optical path of the laser irradiator to more than 250m.
