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。
Due to its simple structure, easy to use, high measuring accuracy and fast measuring speed, the intersection measuring system composed of dual CCD technology is widely used in tracking measurement of various dynamic flying targets in modern shooting range. Based on the introduction of the principle of linear CCD intersection measurement, the relationship between the coordinate measurement precision and each structural parameter of the intersection system is analyzed emphatically. Computer simulation technology is also used to optimize the distribution system of the system. The simulation results show that under the premise of measuring the size of the target surface and the measurement error of each structural parameter, the best distribution method to minimize the system coordinate measurement error can be obtained through simulation calculation.
