Effects of warship motion on predicted trajectory falling points for trajectory correction projectiles
摘要
Abstract
To calculate the trajectories and analyze the accuracy of trajectory correction projectiles (TCP) fired on warships under radar detecting systems quickly and accurately,the relations between warship motion and radar measuring parameters are established to study the effects of warship motion on predicted trajectory falling points of TCP. The corresponding mathematic relations of influences of measurement errors of swing angles,speed,heading angles and heaving for warships on coordinate transformation precision of radar measured trajectory parameters are established. A prediction trajectory model is proposed using extended Kalman filtering,the effects of measurement errors of some factors during warship motion on predicted trajectory falling points are calculated and analyzed. The calculation results show that: compared with the calculation results of considering the measurement errors of radars only,the errors of coordinate transformation and predicted trajectory falling points of radar measured trajectory parameters increase by 1 times when the measurement errors of swing angles are considered simultaneously and increase by 0. 5 and 2 times in range and azimuth directions respectively when the measurement errors of speed,heading angles and heaving of warships are considered simultaneously.关键词
