摘要 针对激光毁伤低慢小目标ATP系统跟瞄误差造成的光斑抖动问题,建立激光斜程辐照低慢小目标的高斯分布等效光斑模型。通过仿真,得到特定大气能见度条件下瞄准误差角度、目标天顶角和目标高度的关系曲线,及不同初始天顶角条件下到达目标表面光斑形态及功率密度,并分析辐照天顶角及目标飞行高度对目标表面归一化功率密度的影响,得到了典型低慢小目标尼龙材料激光防御过程中对ATP系统跟瞄误差的要求,为激光防御低慢小目标各项参数设定及自适应系统的完善提供了依据。 The laser damage of LSS-target (the low altitude, slow speed small target) ATP tracking-pointing error will lead to the spot jitter. To solve this problem, Gauss distribution equivalent model of laser slant irradiation LSS-target was built. Through the simulation, the curve of pointing error angle, target zenith angle and target height was obtained under specific atmospheric visibility conditions, and spot morphology and power density of target surface were gotten under different initial zenith angle conditions. The effect of irradiation zenith angles and target flight height on target surface normalized power density was analyzed. The requirement of typical LSS-target made of nylon material for ATP system tracking-pointing error was obtained in laser defense,which provides a reference for parameter setting and self- adaptation system improvement in laser defense of LSS-target.
