摘　　要：针对火箭飞行异常下的遥测天线继续实时跟踪难的问题,提出一种飞行异常后的实时跟踪角度的预测方法。首先介绍几种常用坐标系以及坐标系之间的转换关系,并将火箭飞行异常后的运动简化为考虑惯性速度的自由落体运动,给出自由落体速度模型和实时跟踪角度的计算方法步骤。设计仿真实验,验证方法的有效性,可以作为火箭飞行异常后遥测天线实时跟踪角度预测的有效参考。In order to solve the problem that it is difficult for the telemetry antenna to continue to track in real time under the abnormal flight of rocket,this paper proposes a prediction method for the real-time tracking angle after the abnormal flight of rocket.In this paper,several common coordinate systems and their transformation relations are introduced firstly.The motion of rocket after abnormal flight is simplified to the free fall motion,considering the inertial velocity.The free fall velocity model and the calculation method of real-time tracking angle are given in this paper.Simulation experiments are designed to verify the effectiveness of the proposed method.
