闪光式焦平面激光成像雷达方程改进及仿真

推导了一个适用于闪光式焦平面激光成像雷达的雷达方程。该方程以传统的激光雷达方程为基础,使用双向反射分布函数描述目标,可以更准确地反应目标上各点的光反射情况。并且讨论了新的雷达方程与原有理论方法之间的关系。根据得到的雷达方程编写了仿真程序,对成像结果进行了仿真计算,针对难以给出解析表达式的双向反射分布函数,使用Phong光照模型进行参数化处理。通过对仿真结果的分析,认为该雷达方程能够较好地反映焦平面激光成像雷达的工作情况。

Improvement and simulation of flash focal plane lidar equation

An applicable lidar equation to flash focal plane imaging lidar was derived.Based on traditional lidar equation,the bidirectional reflectance distribution function was used to characterize the target,which was more accurate to reflect the reflection of the target surface.The relation between this new lidar equation and the existing theory and method was discussed.According to the new lidar equation,a streak tube imaging lidar simulation program was implemented.The Phong lighting model was used to parameterize the bidirectional reflectance distribution function,which was difficult to be analytically expressed.Simulation result of the analysis shows that the new lidar equation can reflect the working process of the focal plane imaging lidar better.
