摘　　要：论述了在捷联惯导专家评估系统中对多传感器信息进行融合的设计方法,对捷联惯导专家评估系统和多传感器信息融合技术进行了深入的研究,同时详细分析了捷联惯导专家评估系统的硬件组成以及各传感器的工作模式,提出一种采用信息时间坐标和空间坐标转换的融合算法,实现时空匹配统一,以达到对系统中多传感器信息较好融合的效果.仿真实验结果表明:用系统中所述的多传感器融合信息进行滤波解算,准精度可以达到0.3°以下,从而提高了整个专家系统的评估精度.The design method was discussed for merging multi-sensor information in the strap-down inertial navigation expert system. The hardware components of the system as well as the work modes of the sensors were analyzed, and an information fusion algorithm based on the space-time coordinate transformation was proposed. The algorithm achieved the match of time and space to obtain a better multi-sensor data fusion effect. Simulation results show that the accuracy can reach under 0. 3° by the filtering of multi-sensor information fusion. So it can enhance the assessment precision of the whole expert system.
