Aiming at the simulation of mine target detected by minehunting sonar，a detection imaging simulation method based on the coupling analysis of kinematic information and underwater acoustic field propagation is proposed. First，the Bellhop3D acoustic field analysis program is used to calculate the impulse response of the underwater acoustic channel signal. Combined with the signal complex analysis method，the parameters of the signal propagation channel are obtained to construct the acoustic scattering model. The influence of the position，attitude and speed of the sonar-loading platform on the echo signal is comprehensively analyzed by means of motion coupling. By comprehensively considering the above factors，the target echo signal is simulated， so as to use the more real equivalent echo signal for image reconstruction. Taking an unmanned underwater vehicle equipped with a high-frequency forward-looking sonar as an example，the sonar detection of mine targets on the bottom of the sea is simulated. The results show that high-frequency sonar detection image of the bottom mine target can be obtained with this method，which is consistent with the actual situation，and can provide a reference for the further construction of mine countermeasures simulation training system.
