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.
