Research on acoustic imaging identification technology of underwater target

Acoustic imaging is an effective approach to improve the guidance accuracy of underwater war weapons, such as torpedo and naval mine. The decoys of underwater combat equipment become more and more realistic. An underwater target identification technology based on acoustic imaging is proposed. The two-dimensional acoustic imaging method based on wind-band correlation technology is researched to get acoustic image. The proposed method is used to identify the true submarines and the acoustic decoy of linear arrays by extracting the two-dimensional characteristics of targets. The simulation research shows that the method is efftive and feasible. © 2015, China Ordnance Society. All right reserved.
