| 中文摘要: |
| 激光陀螺是一种以量化脉冲的形式输出角增量的数字传感器，量化误差如同白噪声一样影响着激光陀螺的测试精度。为了准确评价激光陀螺的性能，减少量化误差对激光陀螺测试数据的影响，本文应用滑动滤波技术对激光陀螺采样数据进行滤波处理，理论分析及实验结果表明，该方法有效地降低了量化噪声从而实现了对激光陀螺的准确评价。 |
| 英文摘要: |
| The laser gyro is virtually a digital sensor which outputs angular increment in the form of quantized pulses. The quantization error influences the test precision as well as white noise in angle. To reduce the effect of quantization error and obtain high precision, moving average filters are developed. The theoretic analysis and experimental results show this method reduces effectively the quantization error and gets an exact evaluation on the laser gyro. |
