一种空爆体坐标测量精度的理论分析

摘要

The feasibility of target detect by using CCD was theoretically analyzed baaed on the luminescent property when a bomb blasting. A three-dimensional measuring error model was deduced by the principle of double-CCD intersection measurement. An optimal position arrangement was obtained to make the three- dimensional measuring error minimum. The error distribution within the measuring space was simulated for this optimal position arrangement, and the basis for choosing the frame rate of CCD detector was gained. The research will provide a theoretical basis for developing the double-CCD photoelectric measurement system.%基于一种空爆体发光的特性,理论分析了采用CCD探测目标的可行性.由双CCD交会测量原理,推导出空爆体坐标误差的数学模型.为使坐标测量误差最小,经最优化分析运算,提出了一种优化布站.在此布站方式下,仿真了坐标测量误差分布,得到了CCD探测器件帧频选择的依据.为双CCD光电测量系统的研制提供了理论基础.
