The invention provides a high-frequency stereo space detection homing acoustic array. Homing acoustic arrays of two forms work jointly to complete detection of three-dimensional space targets. The high-frequency stereo space detection homing acoustic array is composed of a shell as well as a head homing acoustic array and a broadside homing acoustic array which are arranged on the shell; the shell is a cylindrical shell of which one end is provided with a streamlined head; the head homing acoustic array is arranged at a head end surface of the shell; four-element linear arrays and six-element linear arrays are composited to form the head homing acoustic array; a horizontal column of n array elements and a vertical column of n array elements, which are nearest to the center of the head homing acoustic array are selected to have a transmitting function and a receiving function, and the other array elements only have a sound receiving function; the broadside homing acoustic array is arranged at the side surface of the shell; four columns of linear arrays are composited to form the broadside homing acoustic array, wherein the linear arrays are distributed evenly around the circumference of the shell, and each column of linear array is composed of five array elements, wherein three array elements adjacent to the head end surface have an acoustic transmitting function and an acoustic receiving function, and the rest array elements only have an acoustic receiving function. The head homing acoustic array and the broadside homing acoustic array work jointly to complete the detection of the three-dimensional space targets.
