摘　　要：为建立陀螺仪漂移特性模型,需对其进行测试。由测试得到的数据是含有噪声的,且一般是非平稳的。用小波分析测试数据是一种很有效的方法。在简述小波分析中的多分辨分析理论的基础上,用其对某型陀螺仪的实测数据进行了分析—预处理,其结果证实了所研究方法的有效性。A gyro is tested for developing a model of gyro drift character. In general, the measured data contain the noise and is non-stationary. The measured data is analyzed using the wavelet, and this is a very effective method. In this paper, the multiresolution theory of the wavelet analysis is briefly described, then the practical measured data of the gyro is analyzed, and the measured data is pretreated. Final result confirms that this method is effective.
