摘　　要：针对谐振式光学陀螺模拟量式陀螺信号中叠加正弦噪声的问题,提出基于NAND FLASH的数字式陀螺信号提取方式,详细阐述了型号为MT29F64G08AFAAA的FLASH操作过程。进行了样机转动和零偏稳定性测试,并对测试结果进行了Allan方差拟合,辨识出模拟量中的正弦噪声。In view of the sinusoidal noise in the gyro analog signal of the resonant optic gyro, the extraction method of the gyro digital signal based on FLASH NAND was proposed. The operation process of the FLASH in MT29F64G08AFAAA model was described in detail. The rotation and zero bias stability were tested,and the test result was fitted with Allan variance. The sinusoidal noise in the analog signal was identified.
