以双CCD技术构成的交汇测量系统因其结构简单、使用方便、测量精度高、测量速度快等诸多优点,而广泛应用于现代靶场中各种动态飞行目标的跟踪测量。在介绍线阵CCD交汇测量原理的基础上,重点分析了坐标测量精度与交汇系统各结构参数之间的关系,并利用计算机仿真技术对系统的布站方式进行优化设计。仿真结果表明:在给定靶面尺寸及各结构参数测量误差的前提下,通过仿真计算可以得到使系统坐标测量误差最小的最佳布站方式。

Intersection measurement system with dual-CCD is widely used in measuring different kinds of dynamic flying objects in target-field. One of chief technical indexes of linear-CCD intersection measurement system is the accuracy of measuring coordinate. In this paper, the relation between the accuracy of measuring coordinate and structure parameters of intersection system is analysed, according to the principle of CCD intersection measurement, and positioning way is designed by the computer simulation. The result shows that under the condition of the given effective target-area and the measuring errors of structure parameters, the optimum positioning way which makes errors of measuring coordinate least can be obtained by establishing suit math-model and simulation.
