Abstract

Because of the difference of the reflectance characteristic of the ground target and the detonation control of the projectile fuze, the distribution of the projectile explosion position is an uncertain state in the falling process of the terminal trajectory, it is relatively difficult to obtain the parameters of projectile explosion position. Combine with the characteristics of the test environment, this paper proposes a new test and calculation method of projectile explosion position based on two area array CCDs intersection by using the standard rod as the reference object, establishes the object-image relationship calculation function of the standard rod in the CCD imaging system, and deduces the analytical model and calculation method of the projectile explosion position according to the spatial intersection of the two area array CCDs and gives test method. In addition, the paper sets up the error calculation model of projectile explosion position and analyses the influence of uncertainty error factors under the engineering uncertainty testing. Through calculation and experiment analysis, the error distribution of the test system is given, and the proposed test method and the computation model are verified.
