Attitude Measure Method Research For Missile Launch

The missile launch attitude measure method has been the forefront of measuring the direction of research in the field at home and abroad in Test Range, mainly used in the launch segment missile attitude measurements. Considering the requirements of missile launch attitude measure, the methods are researched to establish missile launch attitude measuring system, the researches are mainly carried out.In order to measuring attitude for missile, the demands are presented in attitude measure of missile launch, feasibility and applicability are researched on tilted and plane collimation attitude measure method. Field stitching methods are studied to satisfy demands for gaze field in feasibility. Total parameters are carried out on field of view, focal length, image resolution and other, it is researched that multi-camera field of view of the stitching and single-lens field splicing method, the corresponding optical design, analysis and comparison, finishing choice on stitching methods. It is researched for Image preprocessing, measuring template tracking, measure objective locating methods and applicability, and experimental. On the basis of attitude measurement system for the missile launch actual use procedure, established coordinate system, dual station intersection measurement model and the bisector axis direction vector to solve the missile pitch angle, azimuth approach are researched. Then missile attitude measurement accuracy are analyzed by Monte Carlo simulation approach and theory method. Two measurement methods simulation results show that: under given application conditions for missile attitude measurement, the measurement error is less than 0.2 °. Both simulation method are mutual corroboration, obtained similar calculation results.In this paper, the conclusion of the subsequent attitude measurement system missile launch research work has a good reference.
