[0021] Embodiment 1 Refer to Figure 1 As shown, the present invention provides a medium metasurface lens satellite communication antenna control system, which specifically includes: An anti-shake device and an X-axis offset device array installed on the anti-shake device; The offset device array includes a plurality of X-axis offset devices, with the vertical direction of a single X-axis offset device as the Y-axis direction and the arrangement direction of each X-axis offset device as the X-axis direction; Each of the X-axis offset devices is provided with a plurality of feed antennas along the Y-axis direction, and the electromagnetic wave signal beams of each feed antenna do not overlap; The X-axis offset device is used to control the pointing of the feed antenna, so that the electromagnetic wave signal beams of the feed antennas in the X-axis direction of the same row continuously cover without overlapping, and the coverage range is 180 degrees; The anti-shake device is used to control the orientation of the X-axis offset device array to face the sky; The X-axis offset device is used to control the pointing of the feed antenna, specifically: Taking the pointing angle in the direction perpendicular to the X-axis offset device array as 0 degrees, and obtaining the number C1 of the feed antennas in the X-axis direction of the same row; Calculating the pre-pointing angle D of each feed antenna according to the number C1 of the feed antennas in the X-axis direction of the same row; Using the mean value according to the number C1 to obtain the minimum beam radiation range angle Jmin that makes the sum of the beam radiation range angles of each feed antenna in the X-axis direction of the same row equal to 180 degrees; According to the minimum beam radiation range angle, correct the pre-pointing angles of each feed antenna to obtain the final pointing angle DZ of each feed antenna, and control the pointing of the corresponding feed antenna according to the final pointing angle DZ of each feed antenna.

[0022] It should be noted that D being negative indicates that the pre-pointing angle of the corresponding feed antenna is to the left relative to the direction perpendicular to the X-axis offset device array, and D being positive indicates that the pre-pointing angle of the corresponding feed antenna is to the right relative to the direction perpendicular to the X-axis offset device array. The quantity C1 is a positive integer greater than 1.

[0023] Calculating the pre-pointing angle D of each feed antenna according to the number C1 of feed antennas in the X-axis direction of the same row specifically is: , where n represents the nth feed antenna in the order from left to right.

[0024] For example, if the number C1 of feed antennas in the X-axis direction of the same row is 2, then the pre-pointing angles of the feed antennas from left to right are -90 degrees and 90 degrees in sequence; if the number C1 of feed antennas in the X-axis direction of the same row is 3, then the pre-pointing angles of the feed antennas from left to right are -90 degrees, 0 degrees, and 90 degrees in sequence.

[0032] Both the current facing direction and the best facing direction are represented based on the earth coordinate system. The earth coordinate system usually takes the earth's center as the origin, the x-axis points to the intersection of the prime meridian and the equator, the y-axis points to the intersection of 90° east longitude and the equator, and the z-axis points to the North Pole; the carrier coordinate system takes the location of the mobile communication antenna on the carrier as the origin, the x-axis usually follows the forward direction of the carrier, and the z-axis is along the direction perpendicular to the carrier upward.

[0033] The rotation matrix R = R1·R2·R3 obtained according to the carrier attitude information, where R1 represents the pitch rotation matrix, R2 represents the roll rotation matrix, and R3 represents the yaw rotation matrix; In some embodiments: ; ; ; Using the rotation matrix, the current facing azimuth and the optimal facing azimuth based on the earth coordinate system are respectively converted into a first azimuth vector and a second azimuth vector based on the carrier coordinate system, specifically: V12 = V11 · R, V22 = V21 · R, where V12 and V22 respectively represent the first azimuth vector and the second azimuth vector based on the carrier coordinate system, and V11 and V21 respectively represent the current facing azimuth and the optimal facing azimuth based on the earth coordinate system.

If C3 is greater than or equal to C2, there is no need to adjust the facing azimuth of the X-axis offset device array. If C3 is less than C2, the pre-adjustment azimuth is used as the optimal facing azimuth of the current X-axis offset device array.

[0035] In some embodiments, each of the feed antennas includes a photonic crystal lens array for beamforming the electromagnetic wave signals generated by the feed antennas.
