摘　　要：将双向反射分布函数(BRDF)的概念延伸到复杂目标的激光散射模型研究中,针对半主动激光制导武器系统,建立了坦克目标1.06μm波段的空间激光散射模型,计算了典型条件下坦克目标的激光散射分布并对结果进行了分析,得出了重要结论。研究证明:该方法对复杂目标散射模型的研究是一种简捷、有效的方法。The concept of bidirectional reflectance distribution function is extended into the research on laser scattering model of complicated object in this paper. Aiming at requirement of semi-active laser guided system,a space laser scattering model of tank in 1.06 μm is set up, the laser scattering distribution of tank in typical condition is calculated and the result is analyzed, then,an important conclusion is got. It is proved that this is a brief and effective method of researching scattering model of complicated object.
