摘　　要：针对传递对准数字仿真系统匹配方案、滤波算法的研究需求,提出了一种通用滤波机制——Kalman滤波池.滤波池基于VC++6.0开发环境,结合数据库技术、动态链接库技术实现.通过设计通用符号集、操作面板、匹配模型数据库、导航、滤波算法动态链接库及数据库,将对准匹配模型、滤波参数、矩阵、算法等信息压缩为滤波池记录并管理.通过设计C++功能类和执行流程,依据用户需求导出匹配模型信息、调用动态链接库算法函数、执行对准滤波.测试结果表明,Kalman滤波池运行稳定、占用系统资源少、存储容量小、修改方便,且具有较高的计算精度和运行速度,大大提高了传递对准匹配方案及滤波算法的研究效率,为机载导弹捷联惯导系统设计和传递对准的有效实施提供理论和技术参考.To meet the study requirement of a matching plan involving a filtering algorithm for a transfer alignment in a numerical simulation system, a common filtering mechanism known as a Kalman filtering pool was proposed. The filtering pool was developed under a VC ＋ ＋ 6.0 environment by applying database and dynamic linking librar y （DLL） techniques. Through designing a common sign set, operating panel, matching model database, naviga tion, and filtering algorithm DLL and their databases, information such as alignment matching models, filtering pa rameters, matrices, and algorithms were compressed into the filtering pool record and then managed. Through de signing a C ＋ ＋ function class and implementation procedure, the matching model was exported and the algorithm function in the DLL was applied according to user demand in order to further implement alignment filtering. Testing results show that the Kalman filtering pool functions consistently, occupies fewer system resources, and requires on ly a small storage capacity which can be easily modified. Meanwhile, it shows higher computation accuracy and running speed. Therefore, it greatly improves the study efficiency of a matching plan and filtering algorithm for transfer alignment, and provides theoretical and technological references for the design of an airborne missile strap down inertial navigation system along with efficient implementation of transfer alignment.
