| 摘 要： | 研究目标散射特性对其激光雷达回波特性的影响是进行目标激光雷达主动成像、跟踪以及目标识别的基础。首先推导了考虑探测激光时空分布的目标激光雷达回波公式,通过3DS MAX软件建立了三种典型目标的三维模型,采用单站激光雷达BRDF模型仿真得到了理想漫反射、近似镜面反射以及粗糙表面三种情况下不同目标多角度回波峰值序列,基于此分析了目标散射特性对其激光雷达回波特性的影响,可为目标激光雷达主动探测及成像提供理论参考。

| Abstract: | The effect of target scattering property on laser radar echo characteristics is the base of laser radar active imaging,target tracking and recognition. Firstly,considering the spatial and temporal distribution of detecting laser,the laser radar echo formula is derived. The 3D models of three typical targets are established by 3DS MAX software,and their echo peak value sequences in different angles are simulated by using the BRDF model corresponding to monostatic laser radar,then their echoes are obtained under three different surface material conditions. Based on this,the influence of target scattering property on laser radar echo characteristics is analyzed,and it can provide theoretical references for laser radar active detecting and imaging. |
