导弹发射姿态测量方法研究

Attitude measurement method research for missile launch

针对导弹发射姿态测量问题,提出采用高速摄像机通过斜瞄和平瞄姿态测量方法求解导弹中轴线俯仰角和方位角,仿真典型导弹起飞段近距离姿态测量,分析两种测量方法对导弹飞行姿态测量精度和适用性。仿真结果表明:平瞄和斜瞄姿态测量方法,测量误差在0.2°以内。斜瞄方式使用更便捷,通用性好。平瞄方式测量精度高,数据处理方法、机械结构相对简单,在适合的应用场合优势明显。此分析方法、分析结果为姿态测量方法选取和研究等提供一种可行的途径,也可为其它运动目标的姿态测量提供借鉴。

In order to solve the problem of attitude measurement in missile launch,tilted and plane collimation attitude measurement methods were presented by using high speed videos to calculate pitch and yaw angle for missile middle axes.The missile flight attitude measurement accuracy and applicability of these methods were analyzed by simulating representative near distance missile attitude measurement in flying-off process.The simulating result proves that it may acquire the measuring accuracy of less than 0.2＆#176;by these methods.Plane collimation method is more accuracy.Data processing method and mechanism configuration are relatively sim-ple,and it is more advantage in proper application environment.Tilted collimation method is more universality and suitable for application.Analyzing result and method not only provide a new way to choose attitude meas-urement method,but also give a reference for measuring poses of other moving objects.
