To address the demand for precise imaging of the desired guidance part of a target by an undersea vehicle, this paper attempted to apply multiple-input multiple-output(MIMO) sonar imaging to the acoustic homing platform of an underwater vehicle for the first time. The paper aimed to improve the resolution of active imaging of the acoustic homing platform under limited aperture conditions and obtain clear images to guide the underwater vehicle in determining the desired guidance part of the target. The MIMO sonar transceiver array configuration was discussed in combination with the acoustic homing platform. Simulation results demonstrate that the MIMO sonar can be equivalent to a virtual single-input multiple-output(SIMO) sonar with a larger aperture, possessing both higher angular resolution than traditional SIMO sonar and the advantage of compact size. Deconvolution processing can effectively improve the angular and range resolutions of the MIMO sonar while significantly suppressing sidelobes in both angular and range dimensions. In this paper, the transceiver array and Costas-coded transmission signals are designed based on the acoustic homing platform to process target scattering echoes. The feasibility of the high-resolution imaging method for deconvolution MIMO sonar on the acoustic homing platform is validated. This paper provides a new technical reference and implementation path for high-resolution imaging of MIMO sonar.
