摘　　要：激光雷达的工作原理是向目标物发出探测激光,再通过接收装置接收目标物反射的探测激光,并与发出的探测激光进行比较,经过一系列算法处理,得到目标物的距离、速度、角度、方位等信息。对于在特定的环境中,激光雷达的成像性能受到环境影响,降低雷达接收系统的像面质量,无法很好的成像。本文基于球面函数SF在三维半球面上的表达,通过类比傅里叶变换,将复杂的光信号简化为系数数组进行建模分析,具有特征提取效率高、应用便捷的特点。The working principle of Laser Radar is to emit a detection laser to the target object,and then receive the detection laser reflected by the target object through a receiving device.The laser is compared with the emitted detection laser and processed through a series of algorithms to obtain information such as distance,speed,angle,and orientation of the target object.For specific environments,the imaging performance of Laser Radar is affected by the environment,which reduces the image quality of the radar receiving system and prevents good imaging.This article is based on the expression of the spherical function SF on a three-dimensional hemisphere.By analogizing the Fourier transform,simplify complex optical signals into coefficient arrays for modeling and analysis,which has the characteristics of high feature extraction efficiency and convenient application.
