Abstract

Abstract

In response to the demand for imaging of the expected guidance part of the target by underwater vehicle, this paper attempts for the first time to apply MIMO sonar imaging to underwater vehicle acoustic homing, aiming to improve the resolution of underwater vehicle acoustic homing active imaging under limited aperture, obtain clear images, and guide underwater vehicle to judge the expected part of the target. This paper discusses the MIMO sonar transceiver array using the acoustic self-guided platform, and demonstrates through simulations that the MIMO sonar can be equivalent to a virtual SIMO sonar with a larger aperture, offering higher angular resolution than conventional SIMO sonar as well as a compact size. By using deconvolution processing, the angular and range resolution of the MIMO sonar can be effectively improved, while effectively suppressing the sidelobes in both angular and range dimensions. The innovation of this paper lies in designing the transmitting and receiving arrays based on an acoustic self-guided platform, developing Costas-coded signals, processing target scattering echoes, and validating the feasibility of the deconvolution MIMO sonar high-resolution imaging method on the acoustic self-guided platform, providing a new reference and method for high resolution imaging of MIMO sonar.
