摘　　要：通过建模仿真,从改善陀螺输出带宽以及提高互易性噪声抑制能力出发,对单路闭环谐振式微光学陀螺(R-MOG)和双路闭环R-MOG进行了分析研究。相比于单路闭环R-MOG,双路闭环R-MOG在抑制互易性噪声的同时,能较好地改善输出带宽,并进一步提高陀螺系统的线性度。在此基础上,搭建了双路闭环R-MOG的实验系统,并进行了陀螺零偏稳定性以及输出响应特性测试。实验结果表明,陀螺1h的零偏稳定性为0.53°/s,在±1000°/s转速范围内,陀螺系统的线性度为99.995%。A simulation model is setup to analyze the reciprocal noises reduction and the improvement of the gyro bandwidth of the single closed-loop and double closed-loop resonator micro optic gyro （R-MOG）. Simulation results show that the double closed-loop R-MOG can inhibit the reciprocal noises and enhance the output bandwidth. Furthermore, the double closed-loop R-MOG can improve the gyro linearity. Based on the work mentioned above, an experimental system of the double closed-loop R-MOG is set up. The bias stability and gyro output are tested. Experimental results show that the bias stability of the R-MOG is 0.53 °/s over an hour and the linearity of the R- MOG is 99. 995% over the range of ±1000 °/s.
