摘要
本文介绍了二进正交小波变换的快速算法在基于小波变换的组合滤波器中的应用。该组合滤波器被用于抑制捷联式惯性寻北仪中的周期性噪声和随机干扰。通过对现场采样数据的仿真分析 ,说明该组合滤波器与普通矩形窗滤波器相比 。
The pyramidical Mallat algorithm of orthogonal dyadic wavelet transformation and its application in a wavelet based integrated filter were introduced. The filter is applied to the strapdown inertial north finder to eliminate the periodic noise and random disturbance. The simulation results based on field sampled signals show more effectiveness of the new integrated filter on restraining the dynamic disturbances when compared with the conventional boxcar window FIR.
