| 摘 要： | 针对激光陀螺随机漂移数据的非平稳特性,设计了小波滤波器,使经小波滤波后的数据近似成为平稳序列,并进行了相应的平稳性检验.在小波变换的基础上,结合维纳滤波器处理平稳信号能力强的特点,提出了一种小波域维纳滤波法.仿真试验表明,此方法更显有效性.

| Abstract: | According to the non-stationary characteristic of laser gyro random drift signal, a wavelet filter was designed. The stationary of the data was gotten and tested after wavelet filtering. Based on wavelet transform, a wavelet domain Wiener filter was presented for stationary signal processing. The result of simulation shows that comparing with any single ways this method is more effective. |
