摘要
Abstract
Sound propagation in underwater will induce dispersion due to the natural sea waveguide, and then it will degrade the results of the signal processing. Based on the waveguide invariant, a general warping transform is presented. This warping transform could extract the waveguide mode dispersion curve and remove the effect of the waveguide dispersion. Results from the simulation and experiment show that the transform woks well.关键词
