摘要
避障激光雷达是确保直升机快速机动条件下飞行安全的重要技术手段。为给飞行员预留充足的预警时间,需要使避障激光雷达的参数与直升机的机动特性相匹配。文章由直升机转弯飞行时的机动特征出发,结合避障激光雷达的探测距离、探测视场和随动视场等主要性能参数,对系统的预警时间进行仿真分析研究。研究结果可为避障激光雷达的性能参数与直升机机动特征的匹配设计提供依据,对避障激光雷达的参数优化设计具有重要的指导意义。
Helicopter-borne obstacle warning LiDAR is an important technical equipment to ensure the safety of helicopter under the fast maneuvering condition.In order to reserve sufficient warning time for pilot,the parameters of the obstacle warning LiDAR should be matched with the maneuvering characteristics of helicopter.In this paper,the warning time of the system is simulated and analyzed based on the trajectory of helicopter and the main parameters of obstacle warning LiDAR such as detection range,field of view and field of regard.The results can provide theoretical basis for the design of the performance parameters of the obstacle warning LiDAR according to the maneuvering characteristics of helicopter.Besides,our finding should have an important significance in the parameter optimization of the obstacle warning LiDAR.
