Research and implementation of terrestrial test for underwater acoustic detection device under multi-target environment

Along with the continuous improvement of multi-target detection ability of acoustic detection device with high speed motion platform, it is particularly important to the research of terrestrial test for underwater acoustic detection device under multi-target environment. In this paper the multi-target echo model is presented through the exploitation of the various target models of echoes received by the underwater acoustic detection device with high speed motion platform and the numerical simulations are also presented. Furthermore, a terrestrial test system for underwater acoustic detection device under multi-target environment is designed. The experiment of the terrestrial test system for underwater acoustic detection device shows that it can simulate the multi-target echoes on sea effectively.
