基于光幕阵列的近炸引信炸点坐标测量方法
Coordinate Measurement Method of Proximity Fuze Explosion Point Based on Light Screen Array
摘要
Abstract
Aiming at the problem of lack of measurement data of proximity fuze explosion point in damage assessment and simulation of initiation and combat cooperation,a method for measuring the coordinates of the projectile explosion point based on the light screen array and the principle of flame detection was proposed.A seven light screen array was achieved by two triple light screen detectors and one single light screen detector.When the projectile with the proximity fuze passes through all the detection screens of the light screen array,the light screen array system can measure the flight speed,the pitch angle and azimuth angle in the direction of the projectile speed and target coordinates of the projectile,when the projectile explodes in the field of view of the explosion point flame detector,the three-dimensional coordinates of the explosion point in the projectile space can be further calculated according the explosion time.According to the measurement principle of multi-curtain array and the arrangement of the light screen array,the explosion point coordinate measurement model was established,and the measurement error of the explosion point coordinate measurement was simulated and analyzed.The maximum measurement errors of the three-dimensional coordinates are 7.81 mm,11.66 mm and 9.817 mm.Through the simulated live ammunition experiment data,the maximum measurement errors of the three-dimensional coordinates of the explosion point are 5.9 mm,8.2 mm and 8.4 mm,which are consistent with the theoretical simulation results,verified the feasibility and accuracy of the established measurement model.The method studied in this paper can realize the measurement of explosion point coordinates of proximity fuze projectile under the influence of air drag acceleration and gravity acceleration in the terminal trajectory,this method fully meets the measurement requirements of the three-dimensional coordinates of the explosion point in the proximity fuze space.关键词
