    Abstract: This paper introduces a moored-type underwater acoustic array system recently developed by KRISO for experimental acoustic imaging of underwater environment. It has a sixteen-element linear receiver array and four acoustic projectors which are capable of transmitting separate acoustic signals in synchronous manner. Because each projector can transmit a separate waveform, the multiple-input and multiple-output (MIMO) processing as well as the transmit beamforming can be utilized to enhance the acoustic imaging performance. Mechanically, it adopts two-body design of upper and lower bodies where the acoustic projectors and the receiver array are installed respectively. Active buoyancy control units inside the upper body maintains the total buoyancy and horizontal balance when the array system is deployed in the middle of water column. Principles of the developed system are explained, and preliminary experimental results in large-size water tank are discussed.
