[0056] S110: Obtain angle information of the target object relative to the target antenna.

[0057] In a specific implementation, the angle information of the target object relative to the target antenna may be determined based on the position information of the target object and the position information of the target antenna.

[0058] It should be noted that in the embodiments of the present disclosure, the target antenna can be applied to radar, and can also be applied to satellite communication or point-to-point communication.

[0059] S120: Determine a conduction mode of a switch module connected to a feeding interface of the target antenna according to angle information of the target object relative to the target antenna.

[0060] The scanning angle range of existing phased array antennas is generally 60° off-axis. If the scanning angle is increased, the grating lobe will appear in the direction opposite to the main beam in the antenna scanning pattern, and the gain of the main beam will drop significantly, resulting in a decrease in the overall performance of the antenna. In order to expand the scanning angle of the phased array antenna and make the phased array antenna work at a large scanning angle with reduced performance, a scanning angle expansion method for phased array antennas with reconfigurable directional patterns is proposed. By switching different modes of the antenna unit, the reconstruction operation of the antenna unit directional pattern is realized, and the directional patterns of the antenna unit in different modes are used to realize large-angle scanning. At the same time, this method can increase the distance between the antenna units, thereby reducing the thermal density of the phased array antenna and improving the heat dissipation capacity of the phased array antenna.

Since the target antenna is a directional pattern of three modes with a reconstruction function, the scanning angle coverage range of the target antenna's beam is -90° to 90°, realizing a large-angle scanning of the target antenna.

[0079] That is, in the scanning angle control method of the phased array antenna provided in the embodiment of the present disclosure, if the target object is located within the first angle range in the initial state, the feed signal received by the feed interface of the target antenna is switched by controlling the conduction mode of the switch module, and then the working mode of the target antenna is switched according to the feed signal received by the feed interface, so that the scanning angle of the beam generated by the target antenna in the working mode covers the target object; and when the angle information of the target object relative to the target antenna changes with the movement of the target object, the feed signal received by the feed interface of the target antenna is changed by changing the conduction mode of the switch module, and then the target antenna is switched to another working mode according to the feed signal received by the feed interface, so that the scanning angle of the beam generated by the target antenna in the working mode covers the target object, thereby increasing the scanning angle of the target antenna; in addition, as the scanning angle of the target antenna increases, the distance between the two adjacent antennas increases, and the coupling between the two adjacent antennas decreases.

[0080] The scanning angle control method of the phased array antenna provided by the embodiment of the present disclosure first obtains the angle information of the target object relative to the target antenna; then, according to the angle information of the target object relative to the target antenna, determines the conduction mode of the switch module connected to the feed interface of the target antenna; and according to the determined conduction mode of the switch module connected to the feed interface of the target antenna, outputs a control instruction to the switch module so that the feed interface receives the feed signal; finally, according to the feed signal received by the feed interface, determines the target working mode of the target antenna, and switches the target antenna to the target working mode, so that the target scanning angle of the target antenna in the target working mode covers the target object. The feed signal received by the feed interface is changed by the switch module, thereby changing the working mode of the target antenna. Since the scanning angles of the target antenna in different working modes are different, the working mode of the target antenna includes three working modes, and the three working modes increase the scanning angle of the target antenna, thereby increasing the spacing between two adjacent antennas and reducing the coupling degree between two adjacent antennas.

[0081] Based on the above embodiments, Figure 5 is a flow chart of another phased array antenna scanning angle control method provided by an embodiment of the present disclosure, such as Figure 2 As shown, the phased array antenna scanning angle control method also includes:

[0082] S001. Determine a target object included in a preset scanning angle range of a target antenna.

[0083] In the above embodiment, an antenna scanning angle control method is exemplified when a target object is included in the preset scanning angle range of the target antenna. When a plurality of target antennas are included in the preset scanning angle range of the target antenna, the specific implementation process of the antenna scanning angle control method is as follows: first, the target object included in the preset scanning angle range of the target antenna is determined.

[0084] It should be noted that the preset scanning angle range is -90° to 90°.

[0085] S101: When there are multiple target objects within a preset scanning angle range of a target antenna, sequentially obtain angle information of each target object relative to the target antenna.

[0086] Then, according to the position information of each target object and the position information of the target antenna, the angle information of each target object relative to the target antenna is determined.

[0087] S121. Determine a clock control signal according to the angle information of each target object relative to the target antenna.

[0088] S122: Determine a conduction mode of a switch module connected to a feed interface of a target antenna according to a clock control signal.

[0089] When the preset scanning angle range of the target antenna includes multiple target objects, the clock control signal is determined according to the angle information of each target object relative to the target antenna, and based on the clock control signal, the conduction mode of the switch module connected to the feeding interface of the target antenna in different clock control signals is determined.

[0090] An exemplary combination Figure 2 and Figure 3 When the target antenna includes target object 1 within the first angle range and includes target object 3 within the third angle range, the determined clock control signal is that the first clock signal outputs a high level, the second clock signal outputs a low level, and the third clock signal outputs a high level. At this time, when the switch module connected to the feed interface of the target antenna is in the first clock signal, the first switch unit is in the first type of conduction mode, and the second switch unit is in the second type of conduction mode. When the switch module connected to the feed interface of the target antenna is in the third clock signal, the first switch unit is in the second type of conduction mode, and the second switch unit is in the second type of conduction mode.

[0091] Another exemplary method, combined with Figure 2 and Figure 4 , when the target object 1 is included in the first angle range of the target antenna and the target object 3 is included in the third angle range, the determined clock control signal is that the first clock signal outputs a high level, the second clock signal outputs a low level, and the third clock signal outputs a high level. At this time, when the switch module connected to the feed interface of the target antenna is in the first clock signal, the third switch unit is in the on state, and the fourth switch unit and the fifth switch unit are in the off state. When the switch module connected to the feed interface of the target antenna is in the second clock signal, the third switch unit, the fourth switch unit and the fifth switch unit are all in the off state. When the switch module connected to the feed interface of the target antenna is in the third clock signal, the fifth switch unit is in the on state, and the third switch unit and the fourth switch unit are in the off state.

[0092] The phased array antenna scanning angle control method provided by the embodiment of the present disclosure determines a clock control signal when the target objects are included in the preset scanning angle range of the target antenna through the angle information of each target object relative to the target antenna; and then determines the conduction mode of the switch module connected to the feeding interface of the target antenna according to the clock control signal, so as to ensure that the target antenna covers the target objects within the scanning angle range within the corresponding scanning angle range according to the clock control signal.
