以自适应线性组合器为时变谐波检测器的模型, 根据逆归最小乘自适应滤波算法较好的跟踪性能, 使之应用于时变谐波的跟踪检测。仿真表明该方法比以往的基于最小均方 自适应滤波算法的谐波幅值和相位参数的测定具有更好的跟踪效果。-Adaptive linear combiner with harmonic detector is too variable model, according to inverse normalized least square adaptive filter algorit

粘弹性地震波的衰减不仅与传播时间有关，而且与子波的频率、速度场的分布、射线路经、地下构造展布都有关，因此，仅仅利用反Q滤波对粘弹性的吸收和频散做一维补偿不能完全的恢复地震波长的本来特征。-Viscoelastic seismic wave attenuation is not only associated with the propagation time, and and wavelet frequency distribution of the velocity field, the ra
