The clutter suppression effect of ground objects significantly impacts the detection and tracking performance avian lidar on low-altitude bird flock targets. It is imperative to simulate point cloud data in explore effective methods for suppressing caused by lidar. traditional ray-tracing method enhanced this paper efficiently obtain simulation results objects. By incorporating a beam constraint light-energy constraint, screening efficiency rays improved, making them more suitable simulating large scenes with narrow beams. In paper, collision scheme proposed based constraints, aiming enhance detection. experimental demonstrate that, comparison other conventional methods, yields that exhibit greater conformity actual lidar-collected terms shape characteristics intensity features. Additionally, speed enhanced.
