摘　　要：将涡轮发电机作为速度传感器用于弹道辨识,旨在提供一种新的、工程上易行的弹道辨识方法。通过分析涡轮发电机输出频率特性和弹速变化规律,针对涡轮发电机全弹道不停转和停转两种情况,提出基于涡轮发电机输出频率的弹道辨识总体方案,阐述了弹道辨识的实现过程,并通过实例仿真,重点探讨了弹道辨识所需基础函数的确立过程。仿真研究结果表明,弹道辨识计算量小、误差可控,加之涡轮发电机在引信型号上已有成熟应用,基于涡轮发电机输出频率的弹道辨识方法可行。Based on turbine alternator as a velocity sensor to discriminate trajectory,a new feasible trajectory discrimination method was put forward.Output frequency characteristics of turbine alternators and variable function of trajectory velocity were analyzed,considering various state of turbine alternator rotation.systematic scheme of trajectory discrimination was set up by use of turbine alternator outputs,and realization process of trajectory discrimination was depicted detailed.Moreover,establishment process of basic functions for trajectory discrimination was discussed by instance simulation.The simulation result indicates that calculation workload and error of trajectory discrimination are small and acceptable,therefore,with the addition of turbine alternator application on fuzes,the new trajectory discrimination method is feasible.
