基于太阳方位角原理的炮弹飞行姿态遥测

本文根据常规兵器外弹道弹丸飞行姿态测试这一应用需求，采用数字测量技术及弹载预处理技术，对太阳方位角遥测系统进行了研究。文中给出了太阳方位角测量原理及太阳方位角传感器数学模型，提出并实现了数字太阳方位角遥测系统。该系统实际用于1．8万g炮射环境的靶场测试，首次在我国获得了高g弹丸在外飞行弹道上的太阳方位角数据，并由此获得了弹丸的章动、进动和转动等信息，可用于旋转稳定弹的飞行姿态测量。

TELEMETERING FOR THE ATTITUDE OF PROJECTILE IN FLIGHT BASED ON THE PRINCIPLE OF SOLAR ASPECT ANGLE

In this paper a study is made on the telemetering system of solar aspect angle by digital measurement and pre processing on board to meet the needs of measurement in the flying projectile attitude conventional ordnance. The principle of measurement and mathematical model of the solar aspect angle were given and a scheme of practicable digital telemetering system for the measurement was also propounded. The system has been used in practice for the test of projectiles which survive as high as 18 thousands g . The solar aspect angle data of high g projectiles in flight has been gained for the first time domestically and the mutational motion, precessional motion and spinning motion were derived from these data.
