摘　　要：获取目标的激光散射特性信息是进行激光主动探测的重要步骤,从外形特征、表面材料等方面进行了空中目标特性分析,研究了目标光散射模型以及单站激光雷达双向反射分布函数模型,通过三维建模软件建立了空中目标模型,仿真了4种空中目标的双向反射分布函数分布情况,给出相应分析,所得结果是进行激光主动探测回波波形的获取及后续目标探测与识别的基础。Acquiring information about laser scattering attribute of the target is an important procedure when the active laser detection technique is used. The attribute of aerial targets was analyzed in two aspects corresponding to profile feature and surface material of the target. The diffusion model and the mono station laser radar bidirectional reflectance distribution function model were made. The 3D model was established through modeling software simulating BRDF model of four kinds of aerial targets. The simulation and analysis conclusion is the basement of acquiring the echo waveform of active laser detection and target recognition.
