摘要
综述了民机地形感知警告系统(TAWS)及其前视功能的产生背景、发展过程,介绍了TAWS前视功能的主要原理。对前视功能的报警阈值时间设置方法进行了研究,给出了报警阈值时间设置的分析算法模型,并利用Matlab工具进行了仿真,得到了相应的仿真结果。最后,对进一步提高TAWS前视功能仿真精确度,以及TAWS产品性能优化方法提出了建议。
The development of Terrain Awareness Warning System(TAWS) for civil aircrafts and its forward-looking function were studied,and the principle of the forward looking function was introduced.The method for setting up alarm threshold time in forward looking function was presented,and an algorithm was given for setting up the threshold time.Simulation was made in Matlab,and the corresponding result was obtained.A suggestion is given in the end for improving the simulation precision of forward looking function of TAWS.
