摘　　要：介绍了利用FPGA实现激光陀螺捷联惯导系统数据采集卡的设计。采集电路是激光陀螺捷联惯导系统中非常重要的组成部分,在深入分析激光陀螺和加速度计的输出信号的基础上,完成了基于FPGA的数据采集电路的设计,使用IP核来实现数字滤波模块,通过实验表明,该采集卡计数实时而准确,滤波效果达到设计要求,采用FPGA大大简化了装置,提高了系统的简易性和配置的灵活性。Navigation computer accepts the signals of gyroscope and accelerometer from IMU （Inertial Measurement Unit）, achieves the de- sign of data acquisition based on FPGA. Data acquisition circuit is a very important constituent of the laser gyroscope strapdown inertial navi- gation system, by analyzing the output of laser gyroscope and accelerometer further, completes the design of data acquisition circuit based on FPGA, uses the IP cores to realize the digital filtering module. The experiments show that this acquisition circuit counts numbers real-timely and exactly, the effect of filter achieves the design requirements, taking FPGA simplifies the devices at a large extend so that it also improves its simplification for using and flexibility for collocation.
