摘要

A representation of impulsive sound propagation with a moving source and receiver in an ocean waveguide is derived based on the normal mode theory. The Doppler shift of individual normal mode of narrow-band pulse is analyzed. A Doppler matched condition and Doppler compensation intervals are obtained based on the analysis of the correlation between the emitted and received signals. An experiment of long-range impulse propagation at 55km in a shallow water is used to verify the theoretical results of the Doppler shift compensation.
