飞机防撞系统的建模与仿真

随着空中交通的日益繁忙,民用飞机的空中防撞显得尤为重要。根据飞机空中防撞的要求,首先详细研究了防撞的预警系统,得出了以飞机应答信号为主要信息的预警判断算法。在算法的基础上建立飞机防撞预警系统的仿真模型。采用仿真一体化软件(FLSIM),设计了飞机防撞仿真系统,给出了仿真的详细流程。通过以B747为例的仿真实验,验证了TCAS防撞预警算法的正确性,证明预警有效性,并为进一步开展飞机防撞系统的研究打下了基础。

Modeling and Simulation of Traffic Alert and Collision Avoidance System

With the growing demand of air traffic,anti-collision of civil aircraft appears to be particularly important.In accordance with the requirements of anti-collision,first of all,a detailed study of anti-collision warning model was done.Then the crashworthy algorithm based on response signal of plane is designed.In this basis,the simulation model of TCAS is set up based on FLSIM which is an integrated simulation software and gives details of the simulation flow.It is proved in practice on B747 that crashworthy...
