中文摘要：
根据激光雷达方程及粗糙面脉冲波束散射理论,提出了目标激光脉冲后向散射回波功率即激光一维距离像的计算表达式,并获得斜板、球和圆锥一维距离像的具体形式.数值计算结果与粗糙平板和圆锥激光脉冲回波强度实验数据比较,两者符合良好.数据分析表明,激光一维距离像曲线能够较好反映目标的纵向几何外形信息.我们着重讨论了入射激光脉冲宽度与目标径向尺寸对距离像的影响.上述研究可为激光波段的目标特征提取和识别提供理论依据。
英文摘要：
Pulse laser one-dimensional range profile theory and simulation are investigated.Laser one-dimensional range profile simulation is studied based on pulse wave scattering theory and the radar equation,and the calculated formula of laser onedimensional range profile is obtained.As examples,the range profile simulations are calculated for the sloped-plane,sphere,and cone.It is also analyzed that the influences of target shape,radial length and pulsewidth on the simulation results.This paper offers theory bases and simulation method for abstraction and identification target feature on the laser.
