Three-dimensional coordinates test method with uncertain projectile proximity explosion position based on dynamic seven photoelectric detection screen
文献摘要：
To objectively obtain the three-dimensional coordinates of the projectile fuze proximity explosion when projectile intersects the head of missile target,we propose a dynamic seven photoelectric detection screen test method,which is made up of six plane detection screens and a flash photoelectric dynamic detection screen.The three-dimensional coordinates calculation model of the projectile proximity ex-plosion position based on seven plane detection screens with dynamic characteristics is established.According to the relation of the dynamic seven photoelectric detection screen planes and the time values,the analytical function of the projectile proximity explosion position parameters under non-linear mo-tion is derived.The projectile signal filtering method based on discrete wavelet transform is explored in this work.Additionally,the projectile signal recognition algorithm using an improved particle swarm is proposed.Based on the characteristics of the time duration and the signal peak error for the projectile passing through the detection screen,the signals attribution of the same projectile passing through six detection screens are analyzed for obtaining precise time values of the same projectile passing through the detection screens.On the basis of the projectile fuze proximity explosion test,the linear motion model and the proposed non-linear motion model are used to calculate and compare the same group of projectiles proximity explosion position parameters.The comparison of test results verifies that the proposed test method and calculation model in this work accurately obtain the actual projectile prox-imity explosion position parameters.
