This operation is usually subject to additional distortions due to the motion of the transmitter-channel receiver configuration. This paper points on the effects of the motion while estimating the IR by matching filtering between the transmitted and the received signals and introduces a new motion compensation method. Knowing the transmitted signal, the "apparent" speed of each propagation path can be estimated using wideband ambiguity function [1]. Indeed, some interference appears in the wideband ambiguity plane because of the multipath propagation. A warpingbased lag-Doppler filtering method is proposed allowing us to accurately estimate the IR of the channel. %G English %Z MODE %2 https://hal.science/hal-00386481/document %2 https://hal.science/hal-00386481/file/ICASSP09_Josso.pdf %L hal-00386481 %U https://hal.science/hal-00386481 %~ ENSTA-BRETAGNE %~ UGA %~ CNRS %~ UNIV-GRENOBLE1 %~ UNIV-PMF_GRENOBLE %~ UNIV-GRENOBLE3 %~ INPG %~ OSUG %~ GIPSA %~ GIPSA-DIS %~ GIPSA-SIGMAPHY %~ ENSTA-BRETAGNE-STIC %~ ENSIETA-DTN %~ UGA-TEST-BIS %~ UGA-TEST-TER %~ UGA-TEST-QUATER %~ CMM
