摘　　要：为满足精确制导武器通用惯性导航系统应用需求,设计了一种基于ARM嵌入式平台的惯性导航信号处理系统,实现了光纤陀螺和石英加速度计信号的同步采集与实时处理,完成了系统方案设计、功能划分与实现。经实验验证,采用的加速度计信号AD转换电路不仅有效解决了IF转换电路的输入范围与性能指标互为矛盾的问题,且设计简单、易于实现。系统符合设计需求,具有小型化、低成本、通用性强的特点。In order to meet the application requirements of the general inertial navigation system of precision guidance weapon,an inertial navigation signal processing system based on ARM embedded platform is designed,which realizes the synchronous acquisition and real-time processing of the signals of fiber optic gyroscope and quartz accelerometer sensor.In the paper,the system scheme is designed,the function is divided and realized.The experimental results show that the AD conversion circuit of accelerometer signal not only effectively solves the contradiction between the input range and performance index of the Current-Frequency conversion circuit,but also is simple in design and easy to realize.The system meets the design requirements,and has the characteristics of miniaturization,low cost and strong versatility.
