Claim 10:
11. The phase compensation apparatus according to claim 8, wherein the processor is configured to execute the instructions to control to measure the first array unit and the second array unit, which are placed on a rotary table, so as to obtain measured far-field directivity patterns of the first array unit and the second array unit; and establish a coordinate system based on the far-field directivity patterns, so as to determine a spatial geometrical relationship between the first array unit and the second array unit in a following manner:
exporting the measured far-field directivity patterns of the first array unit and the second array unit, to establish the coordinate system, wherein the coordinate system is represented by using (x, y, z);
establishing a first coordinate system, using the first array unit as an origin O, defining coordinates (x0, y0, z0) of the origin O, and defining a beam directivity (φ, θ) of the array antenna, wherein the defining a beam directivity (φ, θ) of the array antenna comprises:
in the coordinate system (x, y, z), an included angle between a projection of the beam directivity of the array antenna on an xy plane and a positive direction of an x-axis is an angle φ, and an included angle between the beam directivity of the array antenna and an xz plane is an angle θ; and

establishing a second coordinate system, using the second array unit as another point O1 in a coordinate axis, and defining coordinates (x1, y1, z1) of the another point O1.
