提出一种用于新一代运载火箭的扭转、偏摆测量技术,用一束明暗调制的平行光束瞄准火箭上目标棱镜,反射光束被瞄准仪接收并由PSD光电转换,利用汇聚点位置偏离度解算扭转量,利用出光、回光相位差解算偏摆量,通过单光路、单接收器件实现火箭扭转、偏摆的同步测量。具有结构简单、响应速度快、实时性好等优点。研究结果可供未来运载火箭或导弹瞄准系统参考。
A torsion and yawing measurement technique for a new generation of launch vehicle was proposed. Aiming at the target prism on the rocket with a beam of light and light modulated parallel beams, the reflected beam was received by the collimator and converted by PSD. The position deviation of the convergence point Calculate the amount of torsion, the use of light, back to the light phase deviation to calculate the deflection, through a single optical path, a single receiver device to achieve rocket torsion, yaw synchronization measurements. Has the advantages of simple structure, fast response, good real-time. The findings are for future launch vehicles or missile sighting system references.
