摘要

随着激光陀螺在高精度捷联惯导系统中的应用越来越广泛,高精度的数据采集和处理变得越来越重要。本文对激光陀螺输出信号的特性进行了划分,利用FPGA实现了采集信号的测量解调、倍频、计数等功能,实现了激光陀螺信号的采集。在DSP中采用FIR滤波算法提取角速度信号。

Application and Research of High Precision Data Acquisition for Laser Gyro
With the wider and wider application of laser gyro in the high precision strapdown inertial navigation system, high precision data acquisition and processing is becoming more and more important. In this paper, the output signal of the laser gyro characteristics are divided, FPGA is used to measure the signal acquisition demodulation, frequency multiplication, counting and other functions of the laser gyro signal acquisition. FIR filtering algorithm is used in DSP to extract the angular velocity signal.
