摘要

提出一种基于4个线阵TDI-CCD相机组成的三空间靶面结构对多弹丸着靶参数进行测试

以解决弹幕武器等高射速武器多弹丸同时着靶时的立靶密集度测试难题。测试时

2个CCD相机在空中交汇形成与预定弹道方向垂直的立靶靶面I;靶面Ⅱ和靶面Ⅲ分别由1个CCD相机的探测面形成

并分别与靶面I在竖直方向和水平方向上成一定夹角。根据三靶面的空间几何结构、飞行弹丸在4个线阵CCD相机上的成像时间和成像角度

分析了单发弹丸的着靶坐标、飞行速度和穿靶角度。根据多弹丸在三靶面间的成像位置关系以及弹丸飞行速度约束

推导出多发弹丸着靶时的时空散布参数

如弹序、弹丸存速和着靶坐标。仿真和实际试验验证显示测试的多靶面间目标匹配率达到100%。提出的测试方法有效地解决了多发弹丸同时着靶时出现的假目标问题并克服了单CCD立靶测试参数单一等缺点。

Abstract

A kind of three space target structure based on four linear TDI-CCD(Time Delay and Integration CCD) cameras is put forward to measure the target-hitting parameters and to obtain the vertical target dispersion for barrage weapons when multiple projectiles hit the target at the same time. With measurement

two CCD cameras intersect to form the vertical target I

and the target surface is perpendicular to the scheduled ballistic direction. Target surface Ⅱ and Ⅲ are formed by a CCD camera respectively

and a certain angle between target I and Ⅱ is formed in vertical direction

which is the same as that between target I and Ⅲ in horizontal direction. Combined with the geometry of three dimensional target surfaces

the imaging time and imaging angle of the flying projectile on the four linear CCD cameras

the vertical target coordinate and projectile's flying speed are calculated. Meanwhile

based on the relationship of imaging position and the constraint of flying velocity among three target surfaces

the space-time distribute parameters of multiple projectiles are deduced

such as target-hitting sequence

velocity

nutation angle and the target coordinates. Simulation and experiment show that the matching rate of multiple targets among three target surfaces reaches to 100%. The test method effectively eliminates the false target-hitting coordinate when multiple projectiles impact the target simultaneously and calculates precisely multiple projectile parameters all at once.
